Hi,
By default, the BIG-IP system uses its own user directory for user authentication. If you configure a remote authentication method, such as LDAP, RADIUS, or TACACS, the system does not allow you to use local authentication as a backup method if remote authentication fails.
Please add more TACACS servers to avoid this or use local database instead.
