dovecot auth errors for a new user

[Ruben Safir]

I've been running dovecott without trouble for quite a why and now when
I added a new user, it is not accepting the user and I can not track the
problem.  It says find more information in the server log, but it is not
in /var/log/messages or /var/log/mail.err and nothing with lsof
dovecot|grep log show anything to tail
