Strange, but I don't even have dovecot-auth process... :(
When starting, Dovecot gives some warnings, but nothing fatal:

# /etc/init.d/dovecot restart
Stopping Dovecot Imap:                                     [  OK  ]
Starting Dovecot Imap: doveconf: Warning: service auth { 
client_limit=4096 } is lower than required under max. load (4896)
Warning: service auth { client_limit=4096 } is lower than required under
