The CiscoSecure ACS for Windows 4.0 displays the cs user unknown error message when a separate TACACS+ enable password is configured

Core issue

This problem occurs due to the presence of Cisco bug ID CSCsd86017.

The enable password for TACACS+ fails to authenticate if these conditions are met:

  1. The Use Separate Password option is set explicitly.
     
  2. An external authentication source (for example, Windows) is used.

Users can log in but when the enable command is issued, authentication fails, and the Failed Attempts log displays the cs user unknown error message.

Resolution

As a workaround, set the enable password to the Windows password. Alternatively, use the CiscoSecure Password Authentication Protocol (PAP) password.

Note: The CiscoSecure PAP password automatically blanks out and effectively becomes the Windows password.

A separate enable password for TACACS+ works well in CiscoSecure ACS version 3.3.3 and earlier. This problem occurs with CiscoSecure ACS version 4.0(1.27).
