ACS Remote Agent for Windows
ACS Remote Agent for Windows is now supported on Japanese Windows 2000 and Japanese Windows 2003.
SNMP Support and CSA Integration
The following features were introduced in ACS SE 3.3:
•Support for Simple Network Management Protocol (SNMP).
•Integration of Cisco Security Agent in the ACS SE base image.
These features are described in the User Guide for Cisco Secure ACS Solution Engine.
ACS New Features
ACS contains the following new and changed features:
•New RoHS Solution Engine platform. The ACS SE 1113 release consists of a new hardware device that replaces the previous appliance hardware device (the ACS SE 1112 device). The ACS SE 1113 device conforms to Reduction in Hazardous Substances (RoHS) directives of the European Economic Community (EEC)—Directive 73/23/EEC and Directive 89/336/EEC as amended by Directive 93/68/EEC.
•Network Admission Control (NAC) Release 2.0 support—ACS acts as a policy decision point in NAC deployments. Using configurable policies, it evaluates the credentials received from the Cisco Trust Agent, determines the state of the host, and sends a per-user authorization to the network access device: access control lists (ACLs), a policy-based ACL, or a private VLAN assignment. Evaluation of the host credentials can enforce many specific policies, such as OS patch level and antivirus DAT file version. ACS records the policy evaluation results for use with your monitoring system. ACS also allows third-party audit vendors to audit hosts without the appropriate agent technology before granting network access. ACS policies can be extended with external policy servers to which ACS forwards credentials. For example, credentials specific to an antivirus vendor can be forwarded to the vendor's antivirus policy server, and audit policy requests can be forwarded to audit vendors. For more information about the new ACS features to support NAC 2.0, see Support for NAC 2.0.
•Increased number of supported devices—ACS can now support up to 35,000 devices.
•Profile-based authentication and authorization—A new feature called network access profiles allows administrators to classify access requests according to network location, membership in a network device group, protocol type, or other specific RADIUS attribute values sent by the network device through which the user connects. Authentication, access control, posture validation and authorization policies can be mapped to specific profiles. An example of a profile-based policy is the ability to apply a different access policy for wireless access versus remote Virtual Private Network (VPN) access.
•New storage infrastructure—ACS now uses an SQL database to store all the user and configuration information. The new ACS internal database improves scaling and performance, and is less reliant on the Windows Registry. The Windows Registry will be used only for application information. A new database password is required during installation. The password is stored in the Windows registry using Microsoft Crypto API. The database is encrypted by using a hash of customer-provided password and an internal password. You can use the ACS SE CLI to change the password.
•LDAP improvements—ACS caches successful external authentications (by using LDAP), allowing it to immediately look up a user during reauthentication. ACS provides improved SSL support. See LDAP Improvements, for more information.
•Japanese browser support—Supports administration of ACS by using MS Internet Explorer 6.0 SP1 and Netscape Communicator 8.0.4 with Sun Java JRE 1.5.0; or MS Internet Explorer 6.0 SP1 with Microsoft Java Virtual Machine, which is installed on Japanese Windows Operating System (JOS). This feature is supported for entering data in English (not Japanese).
•TACACS+ and RADIUS key support at group level—Ability to set a shared secret at the group level (Network Device Group).
•Purging capability for cached users in ACS—Ability to remove dynamically saved users from the ACS database via User Setup.
–Support for the Microsoft Windows Callback feature.
–Ability for external users to authenticate via an enable password.
–Certificate revocation list checking during EAP-TLS authentication.
•NTLM support—ACS can now operate with Windows NT LAN Manager (NTLM) v1, NTLM v2 (with appropriate Microsoft patches), and LAN Manager (if you require it).
•External Novell NDS database support—Support for group mappings for external Novell NDS databases is now done by using generic LDAP group set mappings.
•Extended replication support—Administrators can now replicate network access profiles and all related configuration, including:
–Posture validation settings
–AAA clients and hosts
–External database configuration
–Global authentication configuration
–Network device groups
–Shared profile components
–Additional logging attributes
•Machine Access Restrictions (MAR) Exemption Lists—You can specify which groups are allowed access to the network; regardless of whether they pass machine authentication. A MAR exemption list can be configured for specific user groups (for example, managers and administrators).
•RADIUS Authorization Component (RAC) support—Includes RADIUS authorization components as a new type of shared profile component. Shared RACs contain groups of RADIUS attributes that you can dynamically assign to user sessions based on a policy.
•Support of additional Cisco hardware devices—ACS 4.0 includes support for Cisco wireless LAN controllers and Cisco adaptive security appliances.
•Online documentation—The online documentation for ACS Solution Engine opens in a separate window, and contains all the information in the User Guide for Cisco Secure ACS Solution Engine. You can search the online documentation by using the Search button, and you can open a PDF version of the user guide.
Support for NAC 2.0
The following features support NAC 2.0:
•EAP-FAST Version 1a support for NAC phase 2—Supports an authenticated tunnel (by using the server certificate) inside of which the provisioning of PACs will occur. EAP types supported inside the tunnel include:
•Agentless host support—Support for Cisco and third-party audit servers that determine posture information about a client, without relying on the presence of a NAC-compliant Posture Agent (PA). These types of clients are also called NAC Agentless Hosts (NAH).
•Linux packages support in posture validation—Supports Linux packages for the Cisco:Host plugin. The following extended attributes are available for Linux packages:
For additional details, see Support for Linux Packages in Posture Validation.
–Support for an external audit server, which determines posture information about a host without relying on the presence of a Posture Agent (PA).
–Posture validation no longer requires NAC databases to verify compliance. The three options from which to choose for validation are:
- internal policies located in ACS
- policies defined on external servers
- policies defined on audit servers for NAC agentless hosts
–Authorization for posture validation is now configured within the Network Access Profiles feature. Posture validation no longer requires special authorization rules.
–This product release includes changes to optimize posture validation. In previous versions, ACS requested all the credentials by using the type-length-value (TLV) protocol. ACS has been optimized to request only the attributes that are required to evaluate posture validation.
The ACS authentication and authorization service, CSAuth, supports multithreading to authenticate with the LDAP external database. Multiple users can simultaneously be searched and authenticated against the LDAP server(s).
LDAP over SSL now includes the option to authenticate by using certificate database files other than the Netscape cert7.db file. This new option uses the same mechanism as other Secure Sockets Layer (SSL) installations in the ACS environment.
When ACS checks authentication and authorization of a user on the LDAP server, it uses a connection with LDAP administrator account permissions to search for the user and for the users groups on the directory subtree. ACS keeps those administrator connections open for successive use. It is possible to limit the maximum number of concurrent administrator connections per generic LDAP external database configuration (primary and secondary).
After an LDAP user is successfully authenticated to the LDAP external database, its distinguished name (DN) on the LDAP server is cached in ACS. The cached DN is used during the next authentication request of the user to save search time.
Support for Linux Packages in Posture Validation
ACS 4.0 supports Linux packages for the Cisco:Host plugin. The following extended attributes are available for Linux packages:
The following Linux packages are supported:
You can add or remove attribute packages in the NAC Attributes Management Page in the ACS SE web interface.
Extended attributes are only supported as descendants of the Cisco:Host application.

This section provides information about installing and upgrading ACS SE and ACS Remote Agents:
Note You should view ACS SE only via a console by using a serial port. We do not recommend using a monitor via the VGA port. If you use a monitor via the VGA port, you will see Windows error messages when starting ACS SE. You can ignore these messages and there is no need to reboot.
Installing from the ACS SE 1111 (HP) Recovery CD
When installing from the Recovery CD for ACS SE 1111 (HP), you might encounter the following issues:
•After installation completes, the ACS SE reboots, performs some configurations, and reboots again. The configurations that occur after the first reboot take a significant amount of time, during which there is no feedback, which is normal system behavior. If, after about an hour, the CLI Initial Configuration screen does not appear, switch off the appliance, and switch it on again. Refer to CSCsc90467.
•After initial configuration ends, if you cannot access the web interface, use the CLI command, reboot, to restart the appliance. Refer to CSCsd20149.
Note These problems occur only on ACS SE 1111 (HP), after installing from the Recovery CD, when performing a full upgrade, including the appliance base image. If you are not upgrading the appliance base image, you do not need to install from the Recovery CD.
See the Supported and Interoperable Devices and Software Tables for Cisco Secure ACS Solution Engine on Cisco.com.
Upgrading and Migrating to ACS SE 4.0
You can upgrade your existing ACS SE appliance with the latest ACS software, appliance management software, and appliance base image. For detailed instructions see Installation Guide for Cisco Secure ACS Solution Engine on Cisco.com.
You can migrate from an existing ACS SE appliance (ACS SE 1111 or 1112) to the ACS SE 1113 by making a backup of the installation on the existing hardware device (SE 1111 or 1112) and then performing a restore of the installation on the new hardware device (SE 1113).
Note ACS Release 3.x is not supported on the SE 1113 platform.
If the existing ACS SE appliance has a previous software version, you must first upgrade the existing appliance to software version 4.0.
For detailed information, see Chapter 5 of the Installation and Setup Guide for the Cisco Secure ACS Solution Engine, "Upgrading and Migrating to Cisco Secure ACS Solution Engine."
ACS supports the following upgrade paths. These paths have been tested and are supported:
•ACS SE release 3.3.3 to ACS SE release 4.0.
•ACS SE, release 3.3.2 to ACS SE 4.0.
•ACS SE, release 3.3.1 to ACS SE 4.0.
•ACS SE, release 3.2.3 to ACS SE 4.0.
•ACS SE versions before ACS SE 3.2.3, first upgrade to ACS SE 3.3.3, then to ACS SE 4.0. For information about upgrading to ACS SE 3.3.3, see Release Notes for Cisco Secure ACS Solution Engine 3.3.3 on Cisco.com.
ACS supports the migration path from ACS for Windows 4.0 to ACS SE 4.0. Before performing migration, you must first upgrade ACS for Windows to version 4.0.
The following migration paths have been tested and are supported:
•Upgrade ACS for Windows, release 3.0.4, via 3.3.3, to ACS for Windows, release 4.0. Migrate to ACS SE 4.0.
•Upgrade ACS for Windows, release 3.2.3, to ACS for Windows, release 4.0. Migrate to ACS SE 4.0.
•Upgrade ACS for Windows, release 3.3.1, to ACS for Windows, release 4.0. Migrate to ACS SE 4.0.
•Upgrade ACS for Windows, release 3.3.2, to ACS for Windows, release 4.0. Migrate to ACS SE 4.0.
•Upgrade ACS for Windows, release 3.3.3, to ACS for Windows, release 4.0. Migrate to ACS SE 4.0.
For ACS SE versions before ACS SE 3.2.3, first upgrade to ACS SE 3.3.3, then to ACS SE 4.0. For information about upgrading to ACS SE 3.3.3, see Release Notes for Cisco Secure ACS Solution Engine 3.3.3 on Cisco.com.
After upgrading to ACS 4.0, you may need to perform additional configuration steps to successfully use ACS and Network Access Profiles (NAP). If you used NAC in ACS 3.3, ACS will not operate in an identical manner in ACS 4.0. For example, you must create a new set of authorization rules for Network Access Profiles that are created during the upgrade process.
Upgrading From Version 3.3
The following actions are performed automatically when you upgrade from ACS 3.3 to ACS 4.0:
1. Local and external posture policies are automatically transformed.
2. A single NAP, (configured for NAC only) is created as a process of the upgrade.
3. Each instance of the selected ACS 3.3 Network Posture Validation Database will automatically be transformed into a posture validation rule. All the rules will be associated with the NAP that was created (in step 2). All PA message and URL redirects are mapped correspondingly.
4. A RADIUS Authorization Component will be created for each mapped group. ACS populates the RAC with all attributes that were configured in the user or group setup menus, except for the posture-token Cisco-av-pair. Since ACS dynamically updates the posture-token Cisco-av-pair attribute at runtime, there is not need to configure it manually.
5. If you manually added posture validation attributes in ACS 3.3, they will be added to the ACS version 4.0 posture dictionary during the upgrade.
Tested Windows Security Patches for ACS Remote Agent
Cisco Systems officially supports and encourages the installation of all Microsoft security patches for Windows 2000 Server and Windows Server 2003 as used for ACS Remote Agent for Windows.
Cisco experience has shown that these patches do not cause any problems with the operation of ACS Remote Agent for Windows. If the installation of one of these security patches does cause a problem with ACS, please contact Cisco Technical Assistance Center (TAC) and Cisco will resolve the problem as quickly as possible.
ACS Remote Agent for Windows has been tested with the Windows Server 2003 patches documented in the following Microsoft Knowledge Base Articles:
ACS has been tested with the Windows 2000 Server patches documented in the following Microsoft Knowledge Base Articles:
This section corrects errors and omissions in the ACS user documentation:
In the User Guide for Cisco Secure ACS Solution Engine 4.0, the tables that summarize database compatibility for the protocols that ACS supports state incorrectly that ACS SE supports ODBC databases. Table 2 and Table 3 in Supported Databases correct this error.
Replication with Different Send and Receive Configurations
The user guide states that the primary ACS compares the list of database components that it is configured to send with the list of database components that the secondary ACS is configured to receive. If the secondary ACS is not configured to receive any of the components that the primary ACS is configured to send, the database replication fails.
The previous information is incorrect (bug CSCsg93907).
The primary ACS first synchronizes with the secondary ACS, and sends only the components that the secondary ACS is configured to receive. The primary ACS does not send components that the secondary ACS is not configured to receive, even if you configure the primary ACS to send those components. Thus, database replication does not fail when different send and receive configurations exist on the primary and secondary ACS.
Submit and Apply Button Changed to Apply Button
In several parts of the User Guide for Cisco Secure ACS Solution Engine 4.0, the documentation instructs the reader to click Submit + Apply to save and apply configuration changes. In release 4.0, the Apply button replaces the Submit + Apply button.
Click the Apply button to save and apply configuration changes.
Cisco issues a security advisory when security issues directly impact its products and require action to repair. For the list of security advisories for Cisco Secure on Cisco.com, see the Cisco Security Advisory: Multiple Vulnerabilities in Cisco Secure Access Control Server at:
The following problems exist in this release:
Cisco AAA Client Problems
Refer to the appropriate release notes for information about Cisco AAA client problems that might affect the operation of ACS. You can access these release notes online at Cisco.com. For NAC-specific client problems, go to http://www.cisco.com/en/US/netsol/ns466/networking_solutions_package.html.
Known Microsoft Problems

Updates for Online Help Documentation
The following errors exist in the ACS online help:
•The ACS documentation indicates that you can disable the dynamic user cache, which is incorrect.
•Support files are not matched to the number of selected days in the basic system configuration section. If you want the support information to be downloaded to include service log files that are older than the current log files, check the Collect Previous X Days logs check box and type the number of days of log files to be included. The "Current Log File" may not be today's date, rather it may be several days older than today's date.
•The online documentation for the ACS SE 1113 states that the description field for a downloadable IP ACL can contain up to 30,000 characters; however, the description can contain only 1006 characters.
•The online help for the Solution Engine states that clicking the Shutdown button powers down the appliance. Clicking the Shutdown button causes a message to appear, indicating that it is safe to power down the appliance. To power down the appliance, press the Power button on the front panel.
Omissions and errors in the ACS documentation include:
•The ACS documentation erroneously indicates that the ODBC database is supported for EAP and Non-EAP Authentication Protocol-Database Compatibility.
•We do not support distributed ACS deployments in a NAT environment. If a primary or secondary address is in NAT format, the database replication file will indicate a shared secret mismatch. The next release of the documentation will address this omission.
•LEAP is not supported when working with Network Access Profiles. You can use LEAP only if your system is operating in legacy ACS mode.
•IP-based NAR filters work only if ACS receives the Radius Calling-Station-Id (31) attribute. The Calling-Station-Id (31) must contain a valid IP address. If it does not, it will fall over to DNIS rules. This requirement was not specified in the documentation. See bug CSCsc72958.
•When creating a package.cab file that is larger than 2GB, additional .cab files are created due to the size limit of the packer. The sequence is: the first package name is package.cab; the second is package1.cab, and so on, until the N package, packageN.cab, where N is the number of packages minus one. The files are saved in the same location that is specified before the packing begins. These files are not standalone and all of them must be sent to package. Problems with the packed file (package.cab) may arise if there is not enough hard-disk space.
•Replication of the appliance configuration is not mentioned in the short help or in the User Guide for the Cisco Secure ACS Solution Engine.
•When you generate a certificate signing request or a self-signed certificate, you should enter only a file name for the private key file and certificate file, not the full directory path.
•The ACS Solution Engine automatically creates an entry called Self in the AAA Servers Table. This entry identifies the Solution Engine machine. However, in the Proxy Distribution Table and the AAA Server Table for RDMS synchronization, the ACS Solution Engine creates an entry for the hostname of the device that is running the ACS Solution Engine.
•In the System Configuration > Support page, the Collect Previous X Days logs check box applies to the number of days previous to the current service log files, which m.

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.
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 provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
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 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, use 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

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.
