[Dovecot] authentication with userdb and passdb fails

[Jure Lozar]

Hello

I cannot retrieve mail via pop3 using dovecot. I have mail in my mailbox
(postfix works fine, maildir contains more then 5 mail files), I use
virtual user. I also changed auth to plaintext for debugging purpuse.

server:
Dovecot 1.0.7
CenoOS 5.4

client: Thunderbird on Kubuntu, username: j...@hrabri.org pass:jure


I tried different parameters and was closest to success with this:

Relevant parts from dovecot.conf:

auth default {
 mechanisms = plain login CRAM-MD5

 userdb passwd-file {
   args =   /home/vmail/%d/passwd
 }
 passdb passwd-file {
   args =   /home/vmail/%d/shadow
 }


log:

I don't really understand this log. Is says Client out: OK, and then
unknown user. Where? In passwd file? Adding domainname after username in
passwd only makes it worse. And why master in? I did not configure
master user.

Thanks for any help.

You've an extra userdb passwd {} in dovecot.conf. See dovecot -n output
for a list of all passdbs and userdbs. Make sure only the wanted ones
are there.

I love you man :)
You were right - I forgot to comment out original setting.

Thank you,
