New Features

Cisco Secure ACS 3.3 contains the following new features and enhancements:

Network admission control (NAC)—Cisco Secure ACS acts as a policy decision point in NAC deployments. Using policies you configure, it evaluates the credentials sent to it by Cisco Trust Agent, determines the state of the host, and sends the AAA client ACLs that are appropriate to the host state. Evaluation of the host credentials can enforce many specific policies, such as operating system patch level and antivirus DAT file version. Cisco Secure ACS records the results of policy evaluation for use with your monitoring system. Policies can be evaluated locally by Cisco Secure ACS or can be the result returned from an external policy server to which Cisco Secure ACS forwards credentials. For example, credentials that are specific to an antivirus vendor can be forwarded to the vendor antivirus policy server.

EAP Flexible Authentication via Secured Tunnel (EAP-FAST) support—Cisco Secure ACS supports the EAP-FAST protocol, a new publicly accessible IEEE 802.1X EAP type developed by Cisco Systems that protects authentication in a TLS tunnel but does not require use of certificates, unlike PEAP. Cisco developed EAP-FAST to support customers who cannot enforce a strong password policy and wish to deploy an 802.1X EAP type that:

does not require digital certificates

support a variety of user and password database types

support password expiration and change

is flexible, easy to deploy, and easy to manage

For example, a customer who uses Cisco LEAP can migrate to EAP-FAST for protection from dictionary attacks. Cisco Secure ACS supports EAP-FAST supplicants that are available on Cisco-compatible client devices and Cisco Aironet 802.11a/b/g PCI and CardBus WLAN client adapters.

Machine Access Restrictions (MARs)—Cisco Secure ACS includes MARs as an enhancement of Windows machine authentication. When Windows machine authentication is enabled, you can use MARs to control authorization of EAP-TLS and Microsoft PEAP users who authenticate with a Windows external user database. Users who access the network with a computer that has not passed machine authentication within a configurable length of time are given the authorizations of a user group that you specify and that you can configure to limit authorization as needed. Alternatively, you can deny network access altogether.

Network Access Filters (NAFs)—Cisco Secure ACS includes NAFs as a new type of Shared Profile Component. NAFs provides a flexible way of applying network-access restrictions and downloadable ACLs on AAA client names, network device groups, or the IP addresses of AAA clients. NAFs applied by IP addresses can use IP address ranges and wildcards. This feature introduces granular application of network-access restrictions and downloadable ACLs, both of which previously only supported the use of the same access restrictions or ACLs to all devices. NAFs allow much more flexible network-device restriction policies to be defined, a requirement common in large environments.

Downloadable ACL enhancements—Cisco Secure ACS 3.3 extends per-user ACL support to any layer-three network device that supports this feature. This support includes Cisco PIX firewalls, Cisco VPN solutions, and Cisco IOS routers. You can define sets of ACLs that can be applied per user or per group. This feature complements NAC support by enabling the enforcement of the correct ACL policy. When used in conjunction with NAFs, downloadable ACLs can be applied differently per AAA client, enabling you to tailor ACLs uniquely per user, per access device.

Configurable replication timeout—An enhancement to CiscoSecure Database Replication which allows you to specify how long a replication event is permitted to continue before Cisco Secure ACS ends the replication attempt and restarts the affected services. This feature improves your ability to configure replication when network connections between replication partners are slow.

Upgrading from Windows NT 4.0

If you are upgrading from a previous version of Cisco Secure ACS that is running on Windows NT 4.0, you cannot upgrade the operating system to Windows 2000 Server. The setup program for previous versions of Cisco Secure ACS detects which Windows operating system the computer used and customizes Cisco Secure ACS for that operating system. As a result, upgrading the operating system to Windows 2000 Server without taking the necessary steps causes Cisco Secure ACS to fail.

We last published information about how to upgrade the operating system of the computer running Cisco Secure ACS to Windows 2000 in the documentation for Cisco Secure ACS 3.1. For more information, see the Installation Guide for Cisco Secure ACS for Windows Server 3.1, which is available at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/

Table 3 Known Problems in Cisco Secure ACS for Windows Server 3.3 

Bug ID
Summary
Explanation

CSCdv35872

Insufficient length for NDS context entry

When a Novell NDS database configuration in Cisco Secure ACS has a context list longer than 4095 characters, editing the NDS configuration page results in incorrect HTML in the browser interface.

Workaround/Solution: Use a context list no longer than 4096 characters.

CSCdv86708

HTTP Port Allocation is not replicated

Changes to HTTP Port Allocation settings do not appear to replicate. After the HTTP Port Allocation settings are changed on the Access Policy Setup page in the Administration Control section on the primary Cisco Secure ACS server and replication succeeds, the secondary Cisco Secure ACS server does not display the changes to the HTTP Port Allocation settings in the HTML interface.

Workaround/Solution: The changes to the HTTP Port Allocation settings do replicate successfully; however, to see the changes on the secondary Cisco Secure ACS server, restart the CSAdmin service.

CSCdz61464

Solaris Netscape 7.0 - Minor Features Failure

When the administrative browser is Netscape 7.0 on Solaris 8.0, some menus in the HTML interface for Cisco Secure ACS do not work properly.

Workaround/Solution: Use a supported Windows browser.

CSCea25090

Logged In User not showing after going into enable mode on router

With AAA Accounting for exec sessions configured on a NAS, a user shows up in the Logged-In User report on Cisco Secure ACS. With Accounting also configured for going into enable mode, the user no longer appears in the Logged-In User report after authenticating successfully.

Cisco Secure ACS tracks user sessions by IP address and port number. When enable authentication succeeds, Cisco Secure ACS sees that the IP address and port number combination for the existing session have been reused and assumes that the accounting stop packet was not sent or was lost; therefore, the user session is removed from the Logged-In User report even though the session continues in enable mode.

Because you cannot configured the NAS to send new accounting start packets when the enable mode is entered, the Logged-In User report cannot correctly report the user session as ongoing.

Workaround: None.

CSCea55457

Radius Attributes do not appear in user/group profile page

After you enable RADIUS attributes in the Interface Configuration section of the Cisco Secure ACS HTML interface, they do not appear or appear only partially in Group Setup or User Setup, as applicable.

Workaround/Solution: Restart the CSAdmin service.

CSCea74289

cascade replication due to user pass change-dont work

Cascading replication does not occur when the replication trigger is a user password change and the primary Cisco Secure ACS is configured to perform replication manually.

Workaround/Solution: Use scheduled replication on the primary Cisco Secure ACS.

CSCea91690

Event Viewer errors on startup/shutdown in .NET

On Windows .Net Server 2003 shutdown and startup, you may see errors that falsely indicate that Cisco Secure ACS service have failed. At startup, you may see a dialog box that indicates that a service, such as CSLog, encountered a problem and will close. The same error logged to Event Viewer, as in the following example:

Reporting queued error: faulting application 
CSLog.exe, version 0.0.0.0, faulting module 
unknown, version 0.0.0.0, fault address 
0x00000000. 

The problem is that, in Windows Server 2003, the Service Manager queries the Cisco Secure ACS services status during startup and shutdown, but Cisco Secure ACS services may not have started yet or may have stopped already. Even though this is normal behavior for Cisco Secure ACS services, Windows perceives this as an error and logs it to the Event Viewer.

On startup, the user sees all errors from the event viewer, which is why, when users logs into Windows right after startup, they see errors from the previous login session.

This behavior observed on Windows Server 2003 only.

Workaround: You can verify that Cisco Secure ACS services are running by using the Control Panel.

CSCeb16968

ACS shared profile components disappear with XML error messages

After you upgrade Cisco Secure ACS, authorization support for Management Center (MC) applications, such as Management Center for Firewalls, fails. In the Shared Profile Components section of the Cisco Secure ACS HTML interface, each MC that has registered with Cisco Secure ACS has a set of pages for configuring authorization components. If you access a page for editing or adding authorization components, you see an error message about a missing XML file.

Workaround/Solution: You must use CiscoWorks to reregister all MCs with Cisco Secure ACS.

Log into the CiscoWorks desktop with admin privileges.

Go to Server Configuration > Setup > Security > Select Login Module. Configure CiscoWorks to use the CiscoWorks Local module, and then configure CiscoWorks to use the TACACS+ module.

Go to VPN Security Management Solution > Administration > Common Services > Configuration > AAA Servers. Unregister all MCs and then reregister all MCs.

Log out of CiscoWorks.

CSCeb51393

multi-admin needs to be able to add/edit/delete downloadable ACLs

When multiple administrators try to add/edit/delete downloadable ACLs under the shared profile components, there is a conflict. After the first admin submits changes, the other administrator's ACS sessions get locked up.

Workaround: There is no workaround. Administrators must inform each other when they are working on the downloadable ACLs.

CSCeb62898

Group mapping ordering applet is not properly ordered

In a newly created Windows group mapping configuration, group mappings list in the wrong order.

Workaround: On the page for ordering group mappings, order the group mappings and click Submit. As additional mappings are added, they appear properly at the end of the list of mappings.

CSCec61110

authentications on secondary acs may fail after replication

Symptom: In environments where primary and secondary Cisco Secure ACS primary and secondary servers are kept in sync by using the replication feature, user authentication may fail for users who are defined in an external database and the Failed Attempts log will contain an "external DB not configured" error.

Conditions: This problem happens with certain external database types such as LDAP, NDS, and the various token server types. This problem does not happen with the Windows external DB. By configuring external databases in a different order on the primary and secondary Cisco Secure ACS servers, authentication fails on the secondary server for users who are defined in the databases that are configured in a different order. If external databases are configured in the same order on primary and secondary servers, this problem does not happen. For example, if you configure two instances of LDAP external user databases on primary and secondary servers, but configure them in different orders after users are replicated, LDAP authentication attempts fail on the secondary server.

Workaround: For each database type involved in the problem, delete the external databases on all secondary servers and reconfigure them in the same order that they are defined on the primary server. If this solution fails, delete the affected external databases on the primary and secondary servers and reconfigure them.

CSCec72911

2003-password aging page display issue

CSCec89440

Unable to edit some of the disabled accounts

The Disabled Accounts report in the Reports and Activity section of the Cisco Secure ACS HTML interface is unable to edit when you access it by using an administrator account that doesn't have access to all groups.

If a page of the Disabled Accounts report has users who belong to groups that the administrator cannot access, the report doesn't allow the administrator to move to the next page of the report.

If a user the group mapping feature to assign a user account to a group, the user account appears on the Disabled Accounts report, even though the administrator only has access to specific groups.

Workaround: Access the Disabled Accounts report with an administrative account that has permission to access all groups.

CSCed42439

Active Directory via LDAP - Group Mappings skip first group

When Active Directory is configured as Generic LDAP and group mappings are configured, the first group in the LDAP directory is skipped.

CSCed59826

CSAdmin stops responding when editing java using netscape

CSCed62260

Remote Agents entries are being deleted after restore

When restoring a dump file that is created on Cisco Secure ACS software version on Appliance, Remote Agent entries (inside Network Configuration) will be deleted.

This behavior should be taken into consideration, since ACS on Appliance behaves similarly as it behaves on the software version and runs over the existing data and settings.

CSCed77992

Action Code 211 does not return group settings to factory defaults

Action Code 211 doesn't work as documented.

Document states, this code "Resets a Group User record back to its original factory defaults". However, some settings are not reset to factory defaults like Shell (exec) and No escape check boxes.

Replication displays error when nothing to be replicated

In a scheduled replication scheme, a secondary server incorrectly records an error in the replication log when scheduled replication does not occur; because no changes have occurred on the primary server. For example, this error can occur when the primary and secondary servers are only configured to replicate the user database and network configuration, and then a change is made to Network Configuration on the primary server; but no change is made in the user database. At the next scheduled replication, the primary server correctly sends only the network configuration, but the secondary logs an error message that the user database was not received. Disregard this error message.

Workaround: None.

CSCed83648

Renaming of NDG removes it from Selected Items of NAF UI

Once some NDG, which is in the Selected Items window of the NAF UI, changes it's name on Network Devices page, it's being removed from the Selected Items of NAF back to the source NDG window, where its known by its new name.

CSCed93251

Fail to locate ACL for updating when ACL uses the same name as NAF

Procedure to reproduce the problem:

1. Configure one Network Access Filtering (For example, Healthy)

2. Configure one Downloadable IP ACL with the same name as that of NAF (For example, Healthy)

Then the following error message appears:

"Failed to locate the ACL for updating".

Workaround: Create a different name for ACL other than those used by NAF.

CSCed90144

When deleting a NAF it should be deleted from the assigned dACLs

Deleting a NAF removes it from Cisco Secure ACS; however, the NAF is still referenced by any downloadable ACLs that referenced it before the NAF was deleted. This problem causes the downloadable ACLs to fail to download and, as a result, the user to whom the ACLs were to be applied fails to authenticate.

Workaround: When you delete a NAF, examine all downloadble ACL configurations and ensure that the NAF is not referenced by any of them.

CSCee13658

Failed attempts report statement is not clear enough

When user validation fails for any reason (external server down, wrong SSL certificate, or key mismatch with NAS), the csv failed attempts report states that the authentication failure code is 'external db account restriction' or 'CS password invalid'.

Workaround: This problem is cosmetic. No workaround.

CSCee38482

Admin account can see all users who are dynamically mapped

Local admin can see dynamic mapped users.

Workaround: It's a read only. No other workaround at this time until bug is fixed.

SPC type created by EMBU DLL returns errors in Name field

In case of SPC component that was created by MC-based applications, the "Name" field is not limited to desired 31 chars, and allows entering many more, also returning an error message to the user. The following pattern of errors is received:

If name is less then 28chars - The name is accepted

If name is between 28 and 34 chars - "Internal Error, Failed to locate or create record for update" message appears.

If name is more then 34 chars - "Name is invalid or contains illegal characters" message appears.

The maximum length of the name should be limited in UI

CSCee73004

CSLog handles reach more than 11,000 after failed ODBC connections

The message queue was added to CSAuth for message store and dedicated thread which actually log the messages from the queue. The default message number in queue is 20K, but it can be managed by registry key HKEY_LOCAL_MACHINE\SOFTWARE\Cisco\
CiscoAAAv3.3\CSAuth\MaxMsgInLogQueue

The navigation bar (button bar on the left) in the HTML interface may disappear after the following sequence:

1. Click System Configuration > ACS Certificate Setup > Certificate Revocation Lists.

2. Click an "Issuer Friendly Name".

3. Click Cancel three times, which returns you to the System Configuration page.

4. Click Global Authenticate Setup.

5. Click Cancel.

6. The navigation bar disappears.

Workaround: Log out of the HTML interface and log in again.

CSCee81070

ACS install fails if installing on machine with running Remote Agent

If Cisco Secure ACS Remote Agent is already installed on a computer on which you later attempt to install Cisco Secure ACS for Windows Server, the installation of Cisco Secure ACS for Windows Server fails.

Workaround: Stop the remote agent service (CSAgent) before beginning the installation of Cisco Secure ACS for Windows Server.

CSCee81203

DataType in SQL of int is different than int displayed in ACS

ACS shows the example of SQL query to create table. The integer field in that example might be not enough, depending on the particular SQl server, because of different integer interpretation (like unsigned int or signed)

So before you use the table creation example you need to check how this particular SQL server interprets the integer field and modify the query accordingly.

CSCee83677

NAC attrs type change can cause NAC GUI error

When an administrator changes the type of an existing NAC attribute by using the CSUtil (or because of backup/restore) and this attribute is used in NAC policies, the Local Policy Configuration page does not appear and error message "An error has occurred while processing the Authen DLL Configure Page because an error occurred in the DLL processing this request" appears.

For example, the attribute Trend:Software-Name is used in one of the rules and then its type was changed to integer. The bug can occur in the following situations:

1. Attribute was deleted and then added with different type by using the CSUtil.

2. Because policies are stored in VarsDB (user database) and dictionaries in registry, administrator can get the different attribute types in dictionary and in policy by doing the restore only on one of the components: user database or configuration.

3. Attribute type was modified do to CSCee83667

Workaround: On the NAC GUI page of the supplier configuration, an administrator can remove the problematic policy from the local policies list and thus the policy page appears without any problems. Go to the supplier config page, press "Local policies" button, remove the problematic policy from the selected list and submit this change.

CSCee83687

Wrong application name is being displayed

When more than one network admission control (NAC) attribute (also known as a credential) has the same application type ID, but the application names are different, Cisco Secure ACS always displays the application name associated with the lowest vendor ID.

For example, if there are two credential types, VENDOR:AV (3000:03) and Cisco:Example (9:3), on the mandatory credentials list for configuring a NAC database, where "VENDOR:AV" should appear, Cisco Secure ACS will display "VENDOR:Example".

This problem is not obvious at first because the default attributes in Cisco Secure ACS that have the same application ID, but different vendor IDs; coincidentally do use the same application name. The problem arises when you add attributes that use a different application name with an application ID that is used by other attributes.

Workaround: Avoid adding NAC attributes whose application name is different than the application name that are used by other NAC attributes with the same application ID.

CSCee83875

Restoring to ACS Win from ACS Sol. Engine lost Interface Cfg. data

When backing up from a Cisco 1112 appliance to Cisco Secure ACS for Windows Server, all Interface Configuration attributes, including TACACS+ and RADIUS attributes, were not the same as they were on the appliance.

Also, when HTTPS was enabled on the appliance, HTTPS wasn't enabled after restoring the backup to Cisco Secure ACS for Windows Server. Instead, only HTTP was used.

These problems did not occur when a backup from Cisco Secure ACS for Windows Server was restored in Cisco Secure ACS Solution Engine.

CSCee83977

Change in NAF is not valid until the services are restarted

Given an IP-based NAR with NAF as its AAA client, if a change occurs in the NAF configuration, such as selection of a different NDG or a change to an IP range, the NAF change does not affect the NAR that is using the NAF until the ACS services are restarted.

Workaround: Restart ACS services.

CSCee85046

odbc logger can not log attribute with name > 32 chars

An imported NAC attribute that has more then total (vendor name + application name + attribute name) of 30 characters cannot be logged with ODBC logging.

When trying to log this attribute, the "show create table" generates an SQL statement with a column name <vendor name>_< application name>_<attribute name>.

The SQL has no problem in this column. But when ACS is trying to write to SQL, it will not succeed. When checking the CSlog.log the column name was found, but only the first 32 characters were there, the rest was cut. After renaming the column in the SQL to fit length of 32 characters, it was successfully logged.

For example the flowing attribute was added:

[attr#0]
vendor-id=666
vendor-name=Automation
application-id=1
application-name=AutoTest
attribute-id=00003
attribute-name=Attr-3-Version
attribute-profile=in out
attribute-type=version

the show create table generate the following SQL statement:

CREATE TABLE failedAttempts (
LoggedAt DATE NULL,
Automation_ AutoTest_ Attr_3_Version VARCHAR(255) 
NULL
)
   

in the CSlog.log, the following error was found:

CSLog 06/15/2004 11:09:59 E 9001 4404 [odbcDLL] ODBC 
error 207: [Microsoft]
[ODBC SQL Server Driver][SQL Server]Invalid column 
name 'Automation_AutoTest_Attr_3_Versi'.

CSCee86310

Csutil -n delete all shared components and NAC policies

Using the -n option with CSUtil.exe deletes all shared profile components (shared NARs, downloadable ACLs, shared command authorization sets, and NAFs) and NAC policies (both local and external), in addition to users. References to the deleted SPCs remain in group profiles.

Backups of the user database, including the dump file created with the -d option of CSUtil.exe, do preserve SPCs and NAC policies in addition to users; therefore, if you use CSUtil.exe to perform database compaction, the SPCs and policies are not lost, since database compaction depends on the -d option to dump the database and the -l option to load it again after -n has been used to initialize the database.

Workaround: None at this time. We strongly recommend routine backups of ACS data and using the -d option to dump the database prior to using the -n option to initialize the database.

CSCee87826

A deleted policy is being reassign when created with the same name

If you delete a NAC policy while it was assigned to NAC databases and then create a new policy with the same name, ACS automatically assigns the newly created policy to the databases to which the deleted policy was assigned. An example scenario:

1. Local policy 'policy1' is assigned to NAC database 'NAC-DB1'.

2. 'policy1' is also assigned to NAC database 'NAC-DB2'.

3. Customer edits 'NAC-DB2' and deletes 'policy1'.

4. 'policy1' disappears from 'NAC-DB1' as well.

5. Customer creates a new policy named 'policy1'.

6. ACS assigns the new policy named 'policy1' to 'NAC-DB1'.

Workaround: Use unique names for policies and never reuse them. Also, before you delete a policy, remove it from all NAC databases; except the one database you use to access the policy when you delete it.

CSCee87899

Replication of NAC policies should be updated in the doc

Documentation incorrectly states that replication of NAC policies is affected by the order in which the NAC databases are created on the primary and secondary ACSs. This documentation is wrong.

Also, the following information is missing from the user guide and online documentation:

NAC databases are not replicated, just as any external user database configurations are not replicated, but local and external NAC policies are replicated; therefore, to ensure that replicated policies are associated with the correct NAC databases on secondary ACSs, you must take the following steps on each secondary ACS that receives replicated NAC policies:

1. For each NAC database on the primary ACS, create a NAC DB of the same name on the secondary ACS.

2. In each NAC database, define same mandatory credentials.

3. For each policy on the primary ACS, create policies with the same names on the secondary ACS.

4. Assign the policies to the NAC databases in the secondary ACS in the same way they assigned on the primary ACS.

When replication occurs, the NAC database configurations on the secondary are not affected, including how policies are assigned to them; but the contents of the policies are updated to reflect any changes on the primary ACS.

CSCee88831

days-since-last-update operator should compare to GMT

Whenever ACS uses the operator days-since-last-update to evaluate a network admission control attribute, ACS compares the time that it got from the NAC client to ACS local time; instead of comparing to Greenwich Mean Time (GMT).

Workaround: Set local time on the ACS server to GMT.

CSCee88908

CSLog crash if a logged attribute is deleted due to replication

The CSLog service on a secondary ACS will not stop or start for the following reason:

1. Primary and secondary ACSs (Windows or Solution Engine) have custom NAC attributes

2. Custom NAC attributes on the primary ACS have been deleted

3. The NAC attributes deleted on the primary ACS are selected to be logged on the secondary ACS

4. Replication succeeded

If you encounter this problem, please call TAC for assistance.

Workaround: If you delete NAC attributes on a primary ACS, be sure that the NAC attributes are deleted on secondary ACSs BEFORE the next replication event.

CSCee89510

dates are logged in local time instead of GMT

NAC attributes that are in date format are in GMT. When ACS logs these attributes, it converts them to ACS local timezone (the timezone of the ACS server).

Workaround: Configure ACS to use the GMT timezone.

CSCef64318

CSTacacs process exhibits high CPU consumption

There was a problem with regexp code used by TACACS code. The regexp code was not multi-thread safe. The problem has been fixed. It is hard to reproduce the problem. However, probability of its occurrence grows with number of concurrent TACACS authorization requests for commands which arguments defined using regular expression syntax.

CSCef61117

ACS on 2003 huge performance impact when writing to registry

Cisco Secure ACS 3.2.3 or 3.3 running on Windows 2003 Standard and Enterprise edition may cause huge delay when writing to the registry.

Therefore when more than six operations write to the Microsoft registry, a failure may occur. Refer to the field notices on Cisco.com for more details.

CSCef16320

Upgrading to 3.3 causes Attributes not to be seen in the R.Agent CSV

When upgrading Appliance 3.2.3 to 3.3, all the NAC Attributes (Cisco:PA, Cisco:HIP, Symantec:AV, NAI:AV, Trend:AV, Application-Posture-Token, System-Posture-Token, Reason) do not move to the "CSV Failed Attempts" and to the "CSV Passed Authentications" in the Remote Agent Logging Configuration.

The same problem occurs when upgrading software to 3.3, back up your data and restore it on Appliance 3.3.

CSCef28686

CSUtil password parsing errors when using marks

CSUtil parses tokens (strings) that are delimited by spaces, tabs and newlines OR set between a pair of quotation marks ("") if a user's password starts with " and includes another " within it (for example, "user1$"3) parsing is incorrect and potentially results in an error. The parsed password is different than the intended (user1$ rather than "user1$"3).

Workaround: None.

CSCef76208

CSAuth Thread not closed, blocks NDS authentication until timeout

CSAuth thread may not close connection, blocking subsequent authentication attempts until the thread timeouts.

CSCeg20307

Unable to authenticate user, found in unknown external DB after upgrade

Users that upgraded to version 3.3.1 or 3.3.2 and were previously authenticated with a Token Server database no longer see an "Unknown DB type 0d00" error in the Authenticate With field.

CSCeg40355

Authentication breaks when lost connectivity to remote log server

Symptom: An ACS server may fail an authentication attempt but log the attempt as successful.

Conditions: If one ACS server is configured to log remotely the passed authentications to another acs server AND that remote acs server is available, everything functions as expected.

If the remote acs server is not avail (link down) the user will be notified that authentication failed (that is, via Telnet) however, the acs server will log this as a successful authentication.c

Workaround: To restore service, do one of the following: bring the link back up on remote ACS or turn off remote logging on local ACS. This problem will be fixed in the next release.

CSCeg51873

ACS chooses wrong NDG for NAR with TACACS/RADIUS NAS on same IP

ACS chooses the wrong NDG for NAR matching if both a TACACS+ and RADIUS NAS are defined with the same IP, and placed in separate NDGs and the authentication is performed via RADIUS. The NDG that contains the TACACS+ NAS will always be used.

CSCeh01822

Radius-Proxy with MS-CHAPv2 authentication failed when using strip

Uninstall of 3.3.3 fails to remove CSMsgDll.dll from the support folder.

Workaround: Stop the Windows performance monitor service to unlock this dll, or reboot the host and delete it manually.

CSCeh38960

Restoring from SW removes the Appliance entry inside the proxy

When restoring the database from the software version to an appliance the restore removes the default proxy entry (appliance itself) from the proxy table.

Workaround: Use the backup from the appliance version or add the default proxy entry manually.

CSCeh41690

Documentation does not include default TACACS+ NAS configuration

Documenting default TACACS+ NAS configuration to accommodate any non-configured NAS in ACS cannot be found in the User Guide. This feature is available, but is documented in the following location:

CSAuth log file:

CSBackupRestore(OUT) Failed to create output directory C:\Program Files\CiscoSecure ACS v3.3\CSAuth\DbSyncScratch\\RegValues for DLL

Conditions: The target folder on the replication slave machine already exists.

Workaround: Delete the target folder.

CSCeh91809

VoIP messages cause CSRadius service unexpected termination

CSCei01730

EAP-TLS authentication to the trusted DC doesnt succeeded

Authentication succeeded only when The EAP-TLS client authenticate to the DC which connected directly to the ACS, but when the user is in the Trusted DC (only in the trusted DC) which connected to the first DC, the authentication didn't succeed and the Fail Attempts message was: "External DB account Restriction."

Same message occurred whether enabling the domain stripping in Windows external database settings or not.

CSCei00338

MAR policy is applied on protocols that do not support machine auth.

Currently MAR can be applied on authentications protocols which do not support machine authentication.

(host/machinename@domain)

Example: cisco-peap, when using this protocol to pass authentication, ACS will map it to the group defined under MAR settings.

CSCei00356

Authentication failed when no initial message is provided under PEAP

When an external Windows database is used to perform authentication using Cisco PEAP, authentication fails when there is no initial message being specified under PEAP configuration under System configuration Global Authentication Setup "Cisco client initial message."

ACS no longer passes authentication for EAP-TLS users, even though their certificate has been revoked.

CSCeg52536

Failed PEAP authentication not shown up in ACS logs

During machine authentication, supplicant doesn't expect the retriable errors, so when machine authentication fails, ACS immediately rejects the attempt and updates the log.

CSCeg62666

Clarify cross-version remote logging is not supported

Information has been added to the release notes to clarify that you cannot backup, restore, replicate information, or login remotely when using different versions of Cisco Secure ACS.

CSCsa85575

Lack of information on an ACS 1111 model

The Cisco 1111 stopped shipping in January 2005. For illustrations found in the Overview chapter, refer to the Installation and Setup Guide for Cisco Secure ACS Appliance 3.2 on Cisco.com. Those illustrations are of the Cisco 1111.

The Cisco 1112 started to ship exclusively in January 2005, so the current Installation and Setup Guide for Cisco Secure ACS Appliance 3.3 includes illustrations of that chassis front and back panel.

MS PEAP pwd change not work for unknown user with NAC

When using the external Windows database together with a different type of external user database, if a user is not cached in the internal database and user must change password on first login, the change password will no longer fail.

CSCef34765

Upgrades from ACS 3.1 to 3.3 will stop RSA Secure ID Authentication

Upgrades no longer stop RSA Secure ID authentication. Although, some Windows behavior problems may still occur. Since Windows AD returns code 1326L if user not present or password not valid - it is very difficult to distinguish between them. Hence, if Window AD is present in the list of external DBs and occupies first place, it will fail all authentication. The most appropriate workaround of this issue is to keep Windows AD _AFTER_ all other configured external DBs.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved by using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, call one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447
