dovecot - Jul 2005 - pop3 authentication failure - password mismatch

I tried to run dovecot 1.0 built by myself but encountered the above problem.

See the error traces below.  First of all, the password and user are
correct, as it worked with the 0.99 rpm version of dovecot.  I also
hand verified with ssh.

I also attached the dovecot config file below.  Any ideas?

Are you sure you're using passwd passdb? Nowadays it only works with
BSDs. Maybe you were using pam before?

If I change passdb to "pam", then dovecot will exist immediate with
errors.  See below:

Jul 22 22:16:34 hsiufen dovecot: Dovecot v1.0-stable starting up
Jul 22 22:16:36 hsiufen dovecot: child 7893 (auth) returned error 89
Jul 22 22:16:36 hsiufen dovecot: Auth process died too early - shutting down
Jul 22 22:16:36 hsiufen dovecot: auth(default): Unknown passdb type
'pam'

Maybe there is something else I should fix here instead of changing passdb?

Thanks.

Yes!  You are right.  "shadow" should work as well.  

I just give it a try and auth worked!  Thanks.

However, I am not hitting another problem : no proper permission.

If I understand correctly I have set it in dovecot.conf file to use
"root" for processing.  How come I don't have enough permission?

Any ideas?
