match the secret key configured in the server; and the wrong TACACS+ server IP address is
configured in the NAM.

action:
Step 1 Log in as a local user.
Step 2 Choose the Admin > Diagnostics > Tech Support.
Step 3 Scroll down to view the /var/log/messages area.
Step 4 Look for the following messages near the end of the log and take the recommended actions:
Error Message ...PAM-tacplus[612]:auth failed:Login incorrect

Recommended Action Log in to the TACACS+ server and configure the authenticate and authorize
NAM user. (See the TACACS+ documentation for information on login configuration.)
