Locked out of admin console

Openfire 3.10.3 running on CentOS 6 with an external MySQL database and authenticating against LDAP. I was able to go through the setup, selected my own LDAP user as an admin and added someone else. It never asked me to set up any kind of “local” account. Logged out, and now cannot log back in. Googling shows this happens a lot, and everyone has a different cause or fix :-/ Restarting Openfire didn’t help, rebooting didn’t help, nothing in the logs.
