This section contains additions to the CiscoSecure ACS for Windows NT product documentation.
- Before you install CiscoSecure ACS for Windows NT, make sure all other applications and windows are closed.
- If you are using Security Dynamics, Inc. (SDI) for token authentication, Cisco recommends that you upgrade to ACE/Client version 4.2 and ACE/Server version 3.3.
- If you have release 2.1 or 2.2 of CiscoSecure ACS for Windows NT installed with the automatic local login box unchecked, when you upgrade to release 2.3, this box will automatically be checked. This allows the administrator to access the Multi-Level Administration window.
If a message displays during installation stating that
The ODBC resource DLL filename
is a different version than the ODBC file type and name, follow these steps:
Step 1 Exit the installation program.
Step 2 Run the ODBCDMIN.EXE file that is located in the SUPPORT\ODBC directory on the CiscoSecure ACS 2.3 for Windows NT Server CD-ROM. Running the ODBCDMIN.EXE file installs the ODBC 3.0 components.
Step 3 When you have finished installing these ODBC components, click SETUP.EXE in the root directory of the CD-ROM to restart installation of CiscoSecure ACS 2.3 for Windows NT Server.
If you get an error message during installation indicating that installation has failed, follow these steps:
Step 1 From the Windows Control Panel Add/Remove Programs window, select:
CiscoSecure ACS 2.3 for Windows NT
Step 2 Click Uninstall.
Step 3 When you have finished uninstalling, click SETUP.EXE in the root directory of the CD-ROM to restart installation of CiscoSecure ACS for Windows NT.
If Uninstall terminated abnormally or if installation still fails, follow these steps:
Step 1 From the SUPPORT\CLEAN directory, run CLEAN.EXE. This will uninstall CiscoSecure ACS 2.3 for Windows NT Server completely and clean up certain statements from the Windows NT Registry that prevent installation of CiscoSecure ACS for Windows NT.
Step 2 When you have finished running CLEAN.EXE, click SETUP.EXE in the root directory of the CD-ROM to restart installation of CiscoSecure ACS for Windows NT.
The following issues have been closed with this release of CiscoSecure ACS for Windows NT.
- CSAuth now works correctly when large numbers of Novell Directory Services (NDS) contexts are used.
- To allow CiscoSecure ACS for Windows NT to retrieve dialed number identification service (DNIS)-based Virtual Private Dial-up Networking (VPDN) tunnel information, the colon (:) character is now allowed in usernames. Additionally, the backslash (\) character is now allowed so users can add domain\username.
- The Dial-Up (PPP/ARAP) field can now contain a comma (,) character.
- You can now set a minimum password length.
- The angle brackets (< >) characters can now be used in the Distribution Table list.
- When used with SDI authentication, CiscoSecure ACS for Windows NT now passes the
Passcode acceptedmessage back to the user.
This section contains a partial list of the open issues for CiscoSecure ACS for Windows NT.
With Netscape Communicator 4.01, when the Hypertext Markup Language (HTML) interface times out, a Java reconnect dialog box opens. However, clicking OK does not reestablish the session. The workaround is either to log in again or to use a different version of the browser.
With Internet Explorer 3.02, when you drag any of the hyperlinks, the navigation bar is hidden, and an Internet Explorer message window opens. The workaround is either to use the browser's Back button or to use a different version of the browser.
When performing Proxy and Windows NT authentication with Windows Dial-Up Networking, CiscoSecure ACS for Windows NT does not strip character strings located in the middle of usernames. For example, if the user ID is corporation@user1 and the domain is DOMAIN01, the authentication package is read as DOMAIN01\corporation@user1. CiscoSecure ACS for Windows NT does not strip "corporation." The workaround is to place the character string to be stripped at the end of the user ID.
If CiscoSecure ACS for Windows NT is installed and you then install Internet Explorer, you must restart the system before CiscoSecure ACS for Windows NT services will start. The workaround is to install Internet Explorer before you install CiscoSecure ACS for Windows NT.
- CSCdk87655 and CSCdk76477
- Earlier releases of Cisco IOS software do not support the IP pooling feature of CiscoSecure ACS for Windows NT with VPDN tunnels. As a result, duplicate IP addresses might be allocated. The workaround is to use Cisco IOS Release 12.02 or later or to use the IP pooling feature of the NAS if you are using VPDN.
- There is an incompatibility issue with the ODBC Structured Query Language (SQL) version 6.5 drivers and CiscoSecure ACS for Windows NT. The workaround is to install the latest ODBC drivers before you install CiscoSecure ACS for Windows NT.
- Changes to passwords made on the SQL server do not take effect immediately. This is an SQL issue that might cause security problems, because users can continue to log in using their old passwords until CSAuth is restarted. The workaround is to restart CSAuth after changing passwords on the SQL server.
- If you are using the Microsoft Access ODBC drivers, the ODBC System Data Source Name (DSN) is not retained after reinstalling CiscoSecure ACS 2.3 for Windows NT Server. This issue does not arise if you are using SQL ODBC drivers. The workaround is to reinstall ODBC after you have installed CiscoSecure ACS for Windows NT.
- After a user account is disabled, Internet Explorer displays the user account status as disabled in the User Setup window but still shows it as enabled in the Group Setup window. The workaround is to restart Internet Explorer.
- CiscoSecure ACS for Windows NT supports only a single connection per user when authenticating on a PIX firewall. This is an issue only for MaxSessions and the Reports and Activity: Logged-In Users window. The accounting logs correctly record the PIX accounting packets; the workaround is to use the accounting logs to track concurrent logins.
- User-defined field names do not appear in the Interface Configuration window of the replicated CiscoSecure ACS for Windows NT immediately. The workaround is to restart CSAdmin after replication.
- If a user authenticates but fails authorization, the NAS port name is blank in the Failed Attempts Log. There is no workaround at this time.
- The NAS Port filter does not work if the Port Name contains a forward slash (/) character. The workaround is to use port names that do not contain the / character.
The following issues have been found when MCIS is used with CiscoSecure ACS for Windows NT.
- After the LDAP server is stopped, any attempt to authenticate via the unknown user policy using LDAP will fail; however, CiscoSecure ACS for Windows NT does not issue an error message back to the NAS. There is no workaround at this time.
- If the MCIS account status is set to a value other than 1, the authentication failure is logged as Unknown. There is no workaround at this time.
- When accessing the External User Databases: Database Group Mapping: MCIS Configuration page, the following message displays:
Define MCIS group set An error has occurred while processing the Authen DLL Configure Page because an error occurred in the DLL processing this request.
- The workaround is to obtain the Active Directory Client software and install it on the CiscoSecure ACS for Windows NT machine.
