dovecot - Oct 2013 - Problem with Dovecot after upgrade to Debian 7.0 (stable)

Dear all,

few days ago I updated Debian to the latest stable and since then 
Dovecot is not working. I use Dovecot as LDA for Postfix and also for 
IMAP access. Also I used SASL and everything was ok before update. After 
I updated to Dovecot 2.1.7 (it used to be 1.x before) it looks like that 
e-mail delever is working but I can not configure IMAP access to work.

All users/passwords are stored as local users in /etc/passwd

When I tried to connect to imap log file shows:

Oct 12 22:16:16 seenet-mtp dovecot: auth-worker(24788): Debug: 
pam(user at mydomain.com,178.x.y.z): lookup service=dovecot
Oct 12 22:17:16 seenet-mtp dovecot: auth: Error: auth worker: Aborted 
request: Lookup timed out

Also tested access opensasl clent and after I tried to log in I have 
received:

* OK Waiting for authentication process to respond..
tar NO [UNAVAILABLE] Temporary authentication failure.

1.x to 2.x is a *major upgrade*

so look in your syslog (not the maillog) and the next time before oyu do a
migration
i suggest https://www.google.at/search?q=upgrade+dovecot+1.x+to+2.x which will
result
at the following instructions *before* start the upgrade

service auth {
  client_limit = 12500
  unix_listener auth-client {
    mode = 0766
  }
  unix_listener auth-userdb {
    mode = 0766
    user = vmail
  }
}

I'm pretty sure you need some of these above, too. You have only the
Postfix auth demon, but none of the Dovecot-internal one.

Please check out the default config and add your configs to it.
