Block admin & root account when remote authentication is configured and reachable?

Stefan, I don't believe that is possible. Admin and root are always available even if remote auth is configured. It's a safety mechanism in case the remote auth server goes down.

Hi Nathan,

thanks for the quick response. Yes that was also my understanding up to now, but yesterday I learned that (if I remember correctly) for Cisco device this seems to be possible. I mean it seems there is an internal mechanism, which checks if the remote authentication server is reachable and if yes, admin- and root-account are not working. Only if it's not reachable, you can use the local accounts. Therefor the customer was asking if this is possible with the F5s as well. I already assumed it's not, but just wanted to double check with the experts.

Ciao Stefan :)

Sounds like you want to enable 'Appliance Mode' This can be done on a temporary basis or as a license change, which F5 will do free of charge. For root temporary
