An ACS Internal DB user cannot ssh to a 3750 switch but telnet works fine.
Authentication method is TACACS+
Other users in the same ACS user group as the problem user can both ssh and telnet to this switch OK.
Debug on the switch shows:
TPLUS: Received authen response status FAIL (3)
The ACS Failed Attempts log shows
ACS password invalid
The ACS Auth.log shows
E 3306 4384 0x27e2 Plain DB pass check for <username> failed"
for the failed username.
The 3750 switch is running 12.2(44)SE6
ACS is 4.2.0.124p11
Really puzzling that telnet using exact same user/password works fine.
Does anyone have any clues/pointers?
TIA, Graeme

Try removing the user from ACS and re-adding it.
Also, does the user have any special characters in its password? If so, try changing it to something using just letters and numbers, as a troubleshooting step.

The password has a mix of upper case lower case and numbers - no special characters. I resolved by re-entering the same password into ACS. Strange.

This suggests possible corruption in the ACS database.
