i have recently configured 2 new Nexus 9k series switches
i configured the tacacs and the aaa and i am able to ping the tacacs server from the switch. but when i try to login with my tacacs id and pw its not authenticating for some reason.
here are the error logs:
%AUTHPRIV-3-SYSTEM_MSG: pam_aaa:Authentication failed for user
%DAEMON-3-SYSTEM_MSG: error: PAM: Authentication failure for illegal user
%TACACS-3-TACACS_ERROR_MESSAGE: All servers failed to respond
suggestions??

Hi ,
what error logs are you seeing at TACAS server ..??
have a look on the TACAS integration with Nexus Switches ...
Hope it Helps...

Seeing this as well in 7.0(3)I7(6). I see open bugs for the other Nexus lines, but not 9k.
I have 9Ks - On 7.0.3.i7.6 and 9.3.1 code I saw this issue.
I was able to use the hidden command sync-snmp-password passwd userabc 1.2.3.4
passwd - is the password of the user
userabc- TACACs authenticated account
1.2.3.4 - TACACs server address.
The command will return to the CLI with no output., Nothing added to the running-config, but the annoying, constant 5 min. interval TACACs error messages stopped. Tested on Version 9.3.1 on 9Ks. Reload shows initial syslog "failed to respond" error, but it did NOT repeat in 5 min. intervals again.
