Hello,
I upgraded our On-Prem server from Release 8-202201 to 8-202206. After the upgrade I'm not able to login to the GUI. We used TACACS+ (ISE) to authenticate. Also the local admin user is not working: "The requested user is not found".
From the CLI I checked the TACACS config via "tacacs_config" and found out, that the configuration was removed during the upgrade. So I configured and enabled TACACS again. I also added a local TACACS user, but without any improvements.
When checking the TACACS+ live log on the ISE I can see, that authorization is failing. Prior to the upgrade there was no user authorization. So there must have been a change in the newer release.
Can someone help me how to configure the ISE so that authorization is working for the On-Prem server?
Thank you and regards
Tobias
