Description This article describes that sometimes, TACACS debug logs do not show events even when it is possible to see them in raw logs.
Scope FortiAuthenticator v6.5.x.
Solution

It is not possible to see new events in the TACACS debugs:

  1. Validate it under TACACS+ -> General. If the log level is debugged, it sometimes could be in another level.
