[syslog-ng] How can i log messages from slapd in one file and not /var/log/messages

Hi All, I want to know how can i have all my log messages inside a file called slapd.log. Actually it´s logging most messages in /var/log/messages and some in /var/log/slapd/slapd.log. I created the following filter for this daemon: filter f_openldap { program(slapd); }; And, by the way, i don´t know whenever to use which of those filter functions. Can somebody explain me? Att, -- Fernando
