Open Issues and Workarounds

The issues for CiscoSecure ACS for Windows NT listed in this section remain open.

HTML Interface Timeout with Netscape Communicator 4.01

  • CSCdj62066

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.

Dragging Hyperlinks in Microsoft Internet Explorer 3.02

  • CSCdj63814

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.

Proxy with Dial-Up Networking

  • CSCdj67375

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.

Installing Internet Explorer when CiscoSecure ACS 2.3(2) for Windows NT Is Already Installed

  • CSCdk12995

If CiscoSecure ACS 2.3(2) for Windows NT is installed and you then install Internet Explorer, you must restart the system before CiscoSecure ACS 2.3(2) for Windows NT services will start. The workaround is to install Internet Explorer before you install CiscoSecure ACS 2.3(2) for Windows NT.

IP Pooling and Virtual Private Dialup Networks (VPDN)

  • CSCdk87655 and CSCdk76477

Releases of Cisco IOS software prior to Release 12.02 do not support the IP pooling feature of CiscoSecure ACS 2.3(2) 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.

Open Database Connectivity (ODBC) and Structured Query Language (SQL) 6.5

  • CSCdk39343

There is an incompatibility issue with the ODBC SQL version 6.5 drivers and CiscoSecure ACS 2.3(2) for Windows NT. The workaround is to follow these steps:

Step 1 Stop all ODBC applications and services.

Step 2 Install the latest ODBC drivers.

Step 3 Install CiscoSecure ACS 2.3(2) for Windows NT.

Note If you do not follow these steps in order, there will be issues with partial ODBC installations and you will have to manually recover by deleting various ODBC dynamic link libraries (DLLs).

Changed Passwords and SQL Servers

  • CSCdk64286

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.

ODBC Authentication System Data Source Name (DSN)

  • CSCdk80413

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(2) 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 2.3(2) for Windows NT.

User Status Inconsistent

  • CSCdk85593

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.

Single Connection Per User on PIX Firewall

  • CSCdk86462

CiscoSecure ACS 2.3(2) 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 Name Not Showing

  • CSCdk68592

User-defined field names do not appear in the Interface Configuration window of the replicated CiscoSecure ACS 2.3(2) for Windows NT immediately. The workaround is to restart CSAdmin after replication.

Network Access Server (NAS) Port Name Blank

  • CSCdk89641

If a user authenticates successfully but fails authorization, the NAS port name is blank in the Failed Attempts Log. There is no workaround at this time.

NAS Port Filter

  • CSCdk89755

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.
