[Dovecot] Running auth as root

[Egbert Jan van den Bussche]

Hi,

I seem to be forced to run the auth proces as root because I want to use 
pam for local users. My gut feeling says that this is Not Good. Is there 
another way?
For the virtual users 'vmail' is good enough because that user may 
access the MySQL database.

This is on Ubuntu server 10.04.1 and Dovecot 1.2.9.

TIA, Egbert Jan
