Well, I solved my own problem by re-granting permissions to the DB.  I still don't know why they changed.  Hmmm, what phase was the moon in?  :)

Subject: [SM-USERS] Login problem

We had to reboot the system today (RH 7.3, MySql, vpopmail, SM 1.2.10) and now, when a login is attempted, this error occurs:
Preference database error (insufficient permissions). Exiting abnormally
I understand it is a permissions problem.  Can anyone point me to what might have changed and what I need to change back?
