[Dovecot] problems connecting to the Problems connecting to mysql

Hi,

I'm trying to setup a mailserver running postfix and dovecot with mysql as database backend. Postfix is already running and delivers mails just fine. Unfortunately, dovecot has great problems connecting to the database (using username + password).

Found that two threads about the same issue but none of them solves the problem

http://dovecot.org/list/dovecot/2005-April/006770.html http://dovecot.org/list/dovecot/2005-August/008394.html

I am using: dovecot-1.0.alpha5 mysql 5.0.17-1

Please, can anyone help? Thanks in advance,

Alfonso
