we have an ACI fabric up and running. Since yesterday I can't access the GUI. I got the login screen, enter my credentials (username, password and authentication TACACS).
Every time I got the message:
TACACS+ Server Authentication DENIED
But login with putty and the same credentials works.
Did you select the correct domain on the login page ? If you configured radius/tacacs you should be able to select the domain (ex. for local authentication the domain would be DefaultAuth or leave it empty but then you should use your username/pwd you defined when initially setting up the fabric for remote authentication select the correct domain)
it was a problem with customers infrastructure. The Tacacs server was replaced by the ISE successor for a test. Unfortunately, I did not know about it..;-)
Changing to the TACACS the GUI Login works again..
Thanks for your help!
