Yes, i set up winbind for passwd and group in nsswitch.conf
[EMAIL PROTECTED]:~$ getent passwd tamas
tamas:*:10001:10001:Tamas:/home/PANNONVOLAN/tamas:/bin/bash
So it works, and as i said, i can log on to other services on the Linux
using the same method (pam+winbind+nss)
Well, Dovecot didn't find the user from passwd. You can set
auth_debug=yes to see if it shows up anything more in logs, but it
probably also says the same thing.
Are you using passwd files or have you configured nss_ldap or something?
