Locked myself out of Openfire console

I'm running on linux with mysql but I suspect it's not too different from what you have.  On mine there is a table in the database called ofUser that lists your users. If you're using LDAP integration then there will likely not be very many records in that table.   There is also a record in the table 'ofProperty' that holds a list of administrators.  The record you want has 'admin.authorizedJIDs' in the name field.  The value field contains a comma separated list of admins. On my system this is the email address of each admin user.
