how to change saslauthd log file?

Hi, I have a suse 9.1 box with cyrus-sasl installed. I was wondering how can I change the saslauthd log file. There is the configuration file in /etc/sysconfig/saslauthd Momentan all the logs are written in the /var/log/messages file, but I would like to write these logs in another file. Are there also some other settings like log level? Thanx in advance. Andy.
