I recently installed Bugzilla on a server and I was trying to configure it to work with LDAP authentication.
Unfortunately, I accidentally disabled DB authentication in the Parameters area of the admin section and the LDAP settings were not configured properly.
Now I am unable to log back in as the administrator and can't log in at all over ldap because the settings were incorrect.
I am unable to figure out where I can manually restore DB authentication for bugzilla either directly in the DB or in some config file.
Appreciate your help
Look in the config file /data/params
You will see an entry called user_verify_class, change this to "DB" and you should be able to log in again.
