Locked out / No root login possible anymore

[DerAndyK]

Hi There, i cant Access my Firewall anymore. The Reason is: i switched my Authentication Server in the Settings Menu to a external  Server. But i have not configured access rules. So i thought change it with my root account. But i cant login anymore with root. I tried everything even by Console. What can i do now?

An LDAP User can logon. But just gets the Message: No page assigned to this user! Click here to logout.

if i remember right, you should be able to connect via serial console and boot into single user mode.

On reboot, i thought, there was the option single user mode. Means not network at all, but if i am right, also no login (you should be root).

Therefore, you should be able to change the authentication via console.
