Hi and thanks for you reply!

F**k! I mean why does it have to be so difficult? In RedHat Linux I got 
the same configuration up without any problems...

Ok, well added that there also. And then I read somewhere that the 
pwcheck_method -line should be in imapd.conf too.

This was actually the other thing I was wondering about; a) where is 
my.cnf in FreeBSD to config MySQL for and b) where does MySQL log the 
queries? I would love to look into what pam really tries to do with 
mysql - or doesn't.

The only thing I can trace back to is the line I get into /var/log/messages:

Aug 26 17:28:27 silakka imapd[3167]: login: my.machine[] kypeli 

Yes, it works but it works dispite it shouldn't since I removed the line 
from database with my username. In fact I read these postings with this 
username that shouldn't work :)

Yep! And this isn't the first time I struggle with Cyrus and notice that 
the docs are out of date and mailing lists/newsgroups are the only way 
to get help. Thank god for them :)

But the wierdest thing is that I think it in fact does use pam to auth 
but it uses the wrong service (a one that authenticates from 
/etc/passwd). Can anyone verify if this is possible? What it the correct 
service line for pam.conf?
