Setting Up and Managing User Accounts

This chapter provides information about setting up and managing user accounts in Cisco Secure Access Control Server for Windows NT/2000 Servers Version 3.0 (Cisco Secure ACS).

Note   Settings at the user level override settings configured at the group level.

Before you configure User Setup, it is important to understand how this section functions. Cisco Secure ACS dynamically builds the User Setup section interface depending on the configuration of your AAA client and the security protocols being used. That is, what you see under User Setup is affected by two factors:

This chapter contains the following sections:

User Setup Features and Functions

The User Setup section of the Cisco Secure ACS HTML interface is the centralized location for all operations regarding user account configuration and administration.

From within the User Setup section, you can perform the following tasks:

About User Databases

Cisco Secure ACS authenticates users against one of several possible databases, including its CiscoSecure user database. Regardless of which database you configure Cisco Secure ACS to use when authenticating a user, all users have accounts within the CiscoSecure user database, and authorization of users is always performed against the user records in the CiscoSecure user database.

Tip The following authentication types appear in the HTML interface only when the corresponding external user database has been configured in the Database Configuration area of the External User Databases section.

Basic User Setup Options

This section presents the basic activities you perform when configuring a new user. At its most basic level, configuring a new user requires only three steps, as follows:

For detailed procedural information, see the "Adding a Basic User Account" section.

What other procedures you perform when setting up new user accounts is a function both of the complexity of your network and of the granularity of control you desire. The other basic procedures detailed in this section include the following:

Beyond these basic user setup options, there are also procedures for configuring a user account for authentication via TACACS+ and RADIUS; these procedures are located under the "Advanced User Authentication Settings" section.

Note   The steps for editing user account settings are essentially identical to those used when adding a user account but, to edit, you navigate directly to the field or fields to be changed. You can not edit the name associated with a user account; to change a user name you must delete the user account and establish another.

Bear in mind two things when setting up new user accounts:

Adding a Basic User Account

This procedure details the minimum steps necessary to add a new user account to the CiscoSecure user database.

To add a user account, follow these steps:

Result: The User Setup Select page opens.

Step 2   Type a name in the User box.

---

Note    The username can contain up to 32 characters. Names cannot contain the following special characters: # ? " * > < Leading and trailing spaces are not allowed.

---

Step 3   Click Add/Edit.

Result: The User Setup Edit page opens. The username being added appears at the top of the page.

Step 4   Ensure that the Account Disabled check box is not selected.

---

Note    Alternatively, you can select the Account Disabled check box to create a user account that is disabled, and enable the account at another time.

---

Step 5   Under Password Authentication in the User Setup table, select the applicable authentication type from the list.

Tip The authentication types that appear reflect the databases that you have configured in the Database Configuration area of the External User Databases section.

Step 6   Specify a single CiscoSecure PAP password by typing it in the first set of Password and Confirm Password boxes.

Tip The CiscoSecure PAP password is also used for CHAP/MS-CHAP/ARAP if the Separate CHAP/MS-CHAP/ARAP check box is not selected.

Tip You can configure the AAA client to ask for a PAP password first and then a CHAP or MS-CHAP password so that when users dial in using a PAP password, they will authenticate. For example, the following line in the AAA client configuration file causes the AAA client to enable CHAP after PAP: ppp authentication pap chap

Step 7   Do one of the following:

Tip For lengthy account configurations, you can click Submit before continuing. This will prevent loss of information you have already entered if an unforeseen problem occurs.

Setting Supplementary User Information

Supplementary User Information can contain up to five fields that you configure. The default configuration comprises two fields: Real Name and Description.

For information about how to display and configure these optional fields, see the "User Data Configuration Options" section.

To enter optional information into the Supplementary User Information table, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Complete each box that appears in the Supplementary User Info table.

Step 3   Do one of the following:

Setting a Separate CHAP/MS-CHAP/ARAP Password

Setting a separate CHAP/MS-CHAP/ARAP password adds more security to Cisco Secure ACS authentication. However, you must have a AAA client configured to support the separate password.

To allow the user to authenticate using a CHAP, MS-CHAP, or ARAP password, instead of the PAP password in the CiscoSecure user database, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Select the Separate CHAP/MS-CHAP/ARAP check box in the User Setup table.

Step 3   Specify the CHAP/MS-CHAP/ARAP password to be used by typing it in each of the second set of Password/Confirm boxes under the Separate (CHAP/MS-CHAP/ARAP) check box.

---

Note    These Password and Confirm Password boxes are only required for authentication by the Cisco Secure ACS database. Additionally, if a user is assigned to a VoIP (null password) group, and the optional password is also included in the user profile, the password is not used until the user is re-mapped to a non-VoIP group.

---

Step 4   Do one of the following:

Assigning a User to a Group

A user can only belong to one group in Cisco Secure ACS. The user inherits the attributes and operations assigned to his or her group. However, in the case of conflicting settings, the settings at the user level override the settings configured at the group level.

By default, users are assigned to the Default Group. Users who authenticate via the Unknown User method and who are not mapped to an existing Cisco Secure ACS group are also assigned to the Default Group.

To assign a user to a group, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   From the Group to which user is assigned list in the User Setup table, select the group to which you want to assign the user.

Step 3   Do one of the following:

Setting User Callback Option

Callback is a command string that is passed to the access server. You can use a callback string to initiate a modem to call the user back on a specific number for added security or reversal of line charges.

To set the user callback option, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Under Callback in the User Setup table, select the applicable option. Choices include the following:

---

Note    The dial-in user must have configured software that supports callback.

---

Step 3   Do one of the following:

Assigning a User to a Client IP Address

To assign a user to a client IP address, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Under Client IP Address Assignment in the User Setup table, select the applicable option. Choices include the following:

---

Note    The IP address assignment in User Setup overrides the IP address assignment in Group Setup.

---

---

Note    If the IP address is being assigned from a pool of IP addresses or by the dialup client, leave the Assign IP address box blank.

---

Step 3   Do one of the following:

Setting Network Access Restrictions for a User

The Network Access Restrictions table in the Advanced Settings area of User Setup enables you to apply NARs in three distinct ways:

---

Note    You can also use the CLI/DNIS-based access restrictions area to specify other values. For more information, see the "About Network Access Restrictions" section.

---

Typically, you define (shared) NARs from within the Shared Components section so that these restrictions can be applied to more than one group or user. For more information, see the "Shared Network Access Restrictions Configuration" section. You must have selected the User-Level Shared Network Access Restriction check box on the Advanced Options page of the Interface Configuration section for this set of options to appear in the Cisco Secure ACS HTML interface.

However, Cisco Secure ACS also enables you to define and apply a NAR for a single user from within the User Setup section. You must have enabled the User-Level Network Access Restriction setting under the Advanced Options page of the Interface Configuration section for single user IP-based filter options and single user CLI/DNIS-based filter options to appear in the Cisco Secure ACS HTML interface.

Note   When an authentication request is forwarded by proxy to a Cisco Secure ACS, any NARs for TACACS+ requests are applied to the IP address of the forwarding AAA server, not to the IP address of the originating AAA client.

To set NARs for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   To apply a previously configured shared NAR to this user, follow these steps:

---

Note    To apply a shared NAR, you must previously have configured it under Network Access Restrictions in the Shared Profile Components section. For more information, see the "Shared Network Access Restrictions Configuration" section.

---

Tip To view the server details of the shared NARs you have selected to apply, you can click either View IP NAR or View CLID/DNIS NAR, as applicable.

Step 3   To define and apply a NAR, for this particular user, that permits or denies this user access based on IP address, or IP address and port, follow these steps:

Tip You should define most NARs from within the Shared Components section so that they can be applied to more than one group or user. For more information, see the "Shared Network Access Restrictions Configuration" section.

Result: The specified AAA client, port, and address information appears in the table above the AAA Client list.

Step 4   To permit or deny this user access based on calling location or values other than an established IP address, follow these steps:

---

Note    You must make an entry in each box. You can use the wildcard asterisk (*) for all or part of a value. The format you use must match the format of the string you receive from your AAA client. You can determine this format from your RADIUS Accounting Log.

---

Tip This is also the selection to use if you want to restrict access based on other values such as a Cisco Aironet client's MAC address. For more information, see the "About Network Access Restrictions" section.

Tip This is also the selection to use if you want to restrict access based on other values such as a Cisco Aironet AP's MAC address. For more information, see the "About Network Access Restrictions" section.

Result: The information, specifying the AAA client, port, CLI, and DNIS appears in the table above the AAA Client list.

Step 5   Do one of the following:

Setting Max Sessions Options for a User

The Max Sessions feature enables you to set the maximum number of simultaneous connections permitted for this user. For Cisco Secure ACS purposes, a session is considered any type of user connection supported by RADIUS or TACACS+, for example PPP, or Telnet, or ARAP. Note, however, that accounting must be enabled on the AAA client for Cisco Secure ACS to be aware of a session. All session counts are based on user and group names only. Cisco Secure ACS does not support any differentiation by type of session—all sessions are counted as the same. To illustrate, a user with a Max Session count of 1 who is dialed in to a AAA client with a PPP session will be refused a connection if that user then tries to Telnet to a location whose access is controlled by the same ACS.

Note   Each Cisco Secure ACS server holds its own Max Sessions counts. There is no mechanism for Cisco Secure ACS to share Max Sessions counts across multiple servers. Therefore, if two Cisco Secure ACS servers are set up as a mirror pair with the workload distributed between them, they will have completely independent views of the Max Sessions totals.

Tip If the Max Sessions table does not appear, click Interface Configuration, click Advanced Options. Then select the Max Sessions check box.

To set max sessions options for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   In the Max Sessions table, under Sessions available to user, select one of the following three options:

---

Note    The default setting is Use group setting.

---

---

Note    User Max Sessions settings override the group Max Sessions settings. For example, if the group Sales has a Max Sessions value of only 10, but a user in the group Sales, John, has a User Max Sessions value of Unlimited, John is still allowed an unlimited number of sessions.

---

Step 3   Do one of the following:

Setting User Usage Quotas Options

You can define usage quotas for individual users. You can limit users in one or both of two ways:

For Cisco Secure ACS purposes, a session is considered any type of user connection supported by RADIUS or TACACS+, for example PPP, or Telnet, or ARAP. Note, however, that accounting must be enabled on the AAA client for Cisco Secure ACS to be aware of a session. If you make no selections in the Session Quotas section for an individual user, Cisco Secure ACS applies the session quotas of the group to which the user is assigned.

Note   If the User Usage Quotas feature does not appear, click Interface Configuration followed by Advanced Options. Then select the Usage Quotas check box.

Tip The Current Usage table under the User Usage Quotas table on the User Setup Edit page displays usage statistics for the current user. The Current Usage table lists both online time and sessions used by the user, with columns for daily, weekly, monthly, and total usage. The Current Usage table appears only on user accounts that you have previously established; that is, it does not appear during initial user setup.

For a user who has exceeded his quota, Cisco Secure ACS denies him access upon his next attempt to start a session. If a quota is exceeded during a session, Cisco Secure ACS allows the session to continue. If a user's account has been disabled because the user has exceeded usage quotas, the User Setup Edit page displays a message stating that the account has been disabled for this reason.

You can reset the session quota counters on the User Setup page for a user. For more information about resetting usage quota counters, see the "Resetting User Session Quota Counters" section.

To support time-based quotas, we recommend enabling accounting update packets on all AAA clients. If update packets are not enabled, the quota is updated only when the user logs off. If the AAA client through which the user is accessing your network fails, the quota is not updated. In the case of multiple sessions, such as with ISDN, the quota is not updated until all sessions terminate, which means that a second channel will be accepted even if the first channel has exhausted the user's quota.

To set usage quota options for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   In the Usage Quotas table, select Use these settings.

Step 3   To define a usage quota based on duration of sessions for a user, follow these steps:

Step 4   To define usage quotas based on the number of sessions for a user, follow these steps:

Setting Options for User Account Disablement

The Account Disable feature defines the circumstances upon which a user's account is disabled.

Note   Do not confuse this feature with account expiration due to password aging. Password aging is defined for groups only, not for individual users. Also note that this feature is distinct from the Account Disabled check box. For instructions on how to disable a user account, see the "Disabling a User Account" section.

Note   If the user is authenticated with a Windows NT/2000 external user database, this expiration information is in addition to the information in the Windows NT/2000 user account. Changes here do not alter settings configured in Windows NT/2000.

To set options for user account disablement, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Do one of the following:

---

Note    This is the default setting.

---

---

Note    The default is 30 days after the user is added.

---

---

Note    The default is 5.

---

Step 3   Do one of the following:

Assigning a PIX ACL to a User

The Downloadable ACLs feature enables you to assign a PIX Access Control List (ACL) at the user level. You must have established one or more PIX ACLs before attempting to assign one. For instructions on how to configure a downloadable PIX ACL using the Shared Profile Components section of the Cisco Secure ACS HTML interface, see the "Adding a Downloadable PIX ACL" section.

Note   The Downloadable ACLs table does not appear if it has not been enabled. To enable the Downloadable ACLs table, click Interface Configuration followed by Advanced Options. Then select the User-Level Downloadable ACLs check box.

To assign a downloadable PIX ACL to a user account, follow these steps:

Result: The User Setup Edit page opens. The username being added and edited appears at the top of the page.

Step 2   Under the Downloadable ACLs section, click the Assign PIX ACL: check box.

Step 3   Select a PIX ACL from the list.

Step 4   Do one of the following:

Advanced User Authentication Settings

This section presents the activities you perform to configure user-level TACACS+ and RADIUS enable parameters.

This section contains the following subsections:

TACACS+ Settings (User)

The TACACS+ Settings section permits you to enable and configure the service/protocol parameters to be applied for the authorization of a user. This section contains the following procedures:

Configuring TACACS+ Settings for a User

You can use this procedure to configure TACACS+ settings at the user level for the following service/protocols:

You can also enable any new TACACS+ services that you may have configured. Because having all service/protocol settings display within the User Setup section would be cumbersome, you choose what settings to hide or display at the user level when you perform configure the interface. For more information about setting up new or existing TACACS+ services in the Cisco Secure ACS HTML interface, see the "Protocol Configuration Options for TACACS+" section.

For more information about attributes, see "TACACS+ Attribute-Value Pairs," or your AAA client documentation. For information on assigning a PIX ACL, see the "Assigning a PIX ACL to a User" section.

Before You Begin

To configure TACACS+ settings for a user, follow these steps:

Step 2   Perform Steps 1 through 3 of the "Adding a Basic User Account" section.

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 3   Scroll down to the TACACS+ Settings table and click the bolded service name check box to enable that protocol; for example (PPP IP).

Step 4   To enable specific parameters within the selected service, select the check box next to a specific parameter and then do one of the following, as applicable:

To specify ACLs and IP address pools, enter the name of the ACL or pool as defined on the AAA client. Leave the box blank if the default (as defined on the AAA client) should be used. For more information about attributes, see "TACACS+ Attribute-Value Pairs," or your AAA client documentation. For information on assigning a PIX ACL, see the "Assigning a PIX ACL to a User" section.

Tip An ACL is a list of Cisco IOS commands used to restrict access to or from other devices and users on the network.

Step 5   To employ custom attributes for a particular service, select the Custom attributes check box under that service, and then specify the attribute/value in the box below the check box.

Step 6   Do one of the following:

Configuring a Shell Command Authorization Set for a User

To configure the Unknown Service setting for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Scroll down to the table under the heading Checking this option will PERMIT all UNKNOWN Services.

Step 3   To allow TACACS+ AAA clients to permit unknown services for this user, select the Default (Undefined) Services check box.

Step 4   Do one of the following:

Advanced TACACS+ Settings (User)

The information presented in this section applies when you have a AAA client with TACACS+ configured.

Tip If the Advanced TACACS+ Settings (User) table does not appear, click Interface Configuration, click TACACS+ (Cisco IOS), and then click Advanced TACACS+ Features.

Details on configuring user options with the Advanced TACACS+ Settings are presented in the following three procedures:

Setting Enable Privilege Options for a User

You use TACACS+ Enable Control with Exec session to control administrator access. Typically, you use it for router management control. From the following four basic options, you can select and specify the privilege level you want a user to have.

---

Note    This is the default setting.

---

---

Note    For information about privilege levels, refer to your AAA client documentation.

---

Tip You must configure NDGs from within Interface Configuration before you can assign user privilege levels to them.

To select and specify the privilege level for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Under TACACS+ Enable Control in the Advanced TACACS+ Settings table, select one of the four privilege options, as follows:

---

Note    (No Enable Privilege is the default setting; when setting up an new user account, it should already be selected.)

---

Step 3   If you selected Max Privilege for Any Access Server in Step 2, select the appropriate privilege level from the corresponding list.

Step 4   If you selected Define Max Privilege on a per-Network Device Group Basis in Step 2, perform the following steps to define the privilege levels on each NDG, as applicable:

---

Note    You must have previously configured a device group for it to be listed.

---

---

Step 3   Do one of the following:

Setting TACACS+ Outbound Password for a User

The TACACS+ outbound password enables a AAA client to authenticate itself to another AAA client via outbound authentication. The outbound authentication can be PAP, CHAP, MS-CHAP, or ARAP, and results in the Cisco Secure ACS password being given out. By default, the user's ASCII/PAP or CHAP/MS-CHAP/ARAP password is used. To prevent compromising inbound passwords, you can configure a separate SENDAUTH password.

Caution   Use an outbound password only if you are familiar with the use of a TACACS+ SendAuth/OutBound password.

To set a TACACS+ outbound password for a user, follow these steps:

Result: The User Setup Edit page opens. The username being added or edited appears at the top of the page.

Step 2   Type and retype to confirm a TACACS+ outbound password for this user.

Step 3   Do one of the following:

RADIUS Attributes

You can configure user attributes for RADIUS authentication either generally, at the IETF level, or for vendor-specific attributes (VSAs) on a vendor-by-vendor basis. For general attributes, see the "Setting IETF RADIUS Parameters for a User" section. Cisco Secure ACS ships with many popular VSAs already loaded and available to configure and apply. For information about creating additional, custom RADIUS VSAs, see the "User-Defined RADIUS Vendors and VSA Sets" section.

To configure the VSA for one of the RADIUS network device vendors supported by Cisco Secure ACS, refer to the appropriate procedure as follows:

User Management

This section describes how to use the Cisco Secure ACS User Setup section to perform a variety of user account managerial tasks.

This section contains the following procedures:

Listing All Users

The Cisco Secure ACS User List displays all user accounts (enabled and disabled). The list includes, for each user, the username, status, and the group to which the user belongs.

Usernames are displayed in the order in which they were entered into the database. This list cannot be sorted.

Note   You can also generate a report of all users, sorted by groups, by using the command-line utility, CSUtil.exe. For more information, see "Cisco Secure ACS Command-Line Database Utility."

To view a list of all user accounts, follow these steps:

Result: The User Setup Select page opens.

Step 2   Click List All Users.

Result: In the display area on the right, the User List appears.

Step 3   To view or edit the information for an individual user, click the username in the right window.

Result: The user's account information appears.

Finding a User

To find a user, follow these steps:

Result: The User Setup Select page opens.

Step 2   Type the name in the User box and then click Find.

Tip You can use wildcard characters (*) in this box.

Tip To display a list of usernames that begin with a particular letter or number, click the letter or number in the alphanumeric list. A list of users whose names begin with that letter or number opens in the display area on the right.

Result: The username, status (enabled or disabled), and group to which the user belongs appear in the display area on the right.

Step 3   To view or edit the information for the user, click the username in the display area on the right.

Result: The user's account information appears.

Disabling a User Account

This procedure details how to manually disable a user account in the CiscoSecure user database.

Note   To configure the conditions by which a user account will automatically be disabled, see the "Setting Options for User Account Disablement" section.

Note   This is not to be confused with account expiration due to password aging. Password aging is defined for groups only, not for individual users.

To disable a user account, follow these steps:

Result: The User Setup Select page opens.

Step 2   In the User box, type the name of the user whose account is to be disabled.

Step 3   Click Add/Edit.

Result: The User Setup Edit page opens. The username being edited appears at the top of the page.

Step 4   Select the Account Disabled check box.

Step 5   Click Submit at the bottom of the page.

Result: The specified user account is disabled.

Deleting a User Account

Caution   If you are authenticating using the Unknown User policy, you must also delete the user account from the external user database. This prevents the username from being automatically re-added to the CiscoSecure user database the next time the user attempts to log in.

To delete a user account, follow these steps:

Result: The User Setup Select page of the HTML interface opens.

Step 2   In the User box, type the complete username to be deleted.

---

Note    Alternatively, you can click List All Users and then select the user from the list that appears.

---

Step 3   Click Add/Edit.

Step 4   At the bottom of the User Setup page, click Delete.

---

Note    The Delete button appears only when you are editing user information, not when you are adding a username.

---

Result: A popup window appears that asks you to confirm the user deletion.

Step 5   Click OK.

Result: The user account is removed from the CiscoSecure user database.

Resetting User Session Quota Counters

You can reset the session quota counters for a user either before or after the user exceeds a quota.

To reset user usage quota counters, follow these steps:

Result: The Select page of the HTML interface opens.

Step 2   In the User box, type the complete username of the user whose session quota counters you are going to reset.

---

Note    Alternatively, you can click List All Users and then select the user from the list that appears.

---

Step 3   Click Add/Edit.

Step 4   In the Session Quotas section, select the Reset All Counters on submit check box.

Step 5   Click Submit at the bottom of the browser page.

Result: The session quota counters are reset for this user. The User Setup Select page appears.

Resetting a User Account after Login Failure

Perform this procedure when an account is disabled because the failed attempts count has been exceeded during an unsuccessful user attempt to log in.

To reset a user account after login failure, follow these steps:

Result: The User Setup Select page of the HTML interface opens.

Step 2   In the User box, type the complete username of the account to be reset.

---

Note    Alternatively, you can click List All Users and then select the user from the list that appears.

---

Step 3   Click Add/Edit.

Step 4   In the Account Disable table, select the Reset current failed attempts count on submit check box, and then click Submit.

Result: The Failed attempts since last successful login: counter resets to 0 (zero) and the system re-enables the account.

Note   This counter shows the number of unsuccessful login attempts since the last time this user logged in successfully.

Note   If the user authenticates with a Windows NT/2000 external user database, this expiration information is in addition to the information in the Windows NT/2000 user account. Changes here do not alter settings configured in Windows NT/2000.

Saving User Settings

After you have completed configuration for a user, be sure to save your work.

To save the configuration for the current user, follow these steps:

Step 2   To verify that your changes were applied, type the username in the User box and click Add/Edit, and then review the settings.
