[Dovecot] Problem with Dovecot after upgrade to Debian 7.0 (stable)

[Milan Milošević]

I have checked that before and did doveconf -n -c... at first but the 
result was same. After that I have removed Postfix, Dovecot, saslauthd 
and all configurations. I installed everything again (by following 
documentations for Dovecot and Postfix) and the problem is still here.

To me it looks like that there is a problem when dovecot tries to 
connect to PAM but I'm not sure...
