I haven't doveadm logs in /var/log/. Are they default in another place or maybe should I turn on something?

doveadm log errors can be helpful too
I can check each logs, I have root privileges.

Can you check your logs?
Aki
When I used backup copy of the dovecot.conf file I have this same error. So I think that maybe something was written to database? I really would

And in auth_mechanisms add line cram-md5. Nothing more in any other file.
I don't want to use cram-md5. I need move back to default settings. Cram-md5 was only for testing purposes. :) But I supposed that I can move back to default by commenting out added lines. But unfortunately it isn't that simple.

Are you still trying to authenticate using cram-md5?
Aki
It still use: passdb { driver = passwd-file args = scheme=cram-md5 /etc/dovecot/cram-md5.pwd }
When I delete above and delete "cram-md5" in auth_mechanisms it still not working.
