Openfire 3.8.2 and external db with local login?

I have inherited an openfire server that is currently running 3.8.2 and working perfectly. It is setup for active directory authentication using ldap calls and an external mssql db. I understand that most of the settings are now stored in the external db instead of locally on the server but my question is, if the ldap calls break, which they have several times recently due to some circumstances beyond my control, how can I get back into the product to change/fix things without having to hack away at the tables in the database?

In other words, is there any way to have openfire still work like it is by using active directory, but also have one userid that can login without needing active directory authentication so if ad breaks, I can still get in?
