[Dovecot] dovecot on os x

Hello im new to this list and also to dovecot.

This will probably equal a some newbie questions but i hope to learn
and teach others :)

And it just happens that i have a question.

After installing im trying to login, i have set all debug params to
true. and in my log i get.

dovecot: Dec 02 17:20:50 Info: auth(default): pam(kvapil, 62.181.XXX.XX): pam_authenticate() failed: Authentication failure

Im using dovecot-1.0-stable.

Any ideas anyone?
