[Dovecot] Using dovecot sasl for authenticating in openldap

Hi,

I am using dovecot imaps and exim, both authenticating using dovecot-sasl. To keep passwords in one place I would like to authenticate openldap users over dovecot-sasl.

So looking at this page: http://www.openldap.org/doc/admin24/security.html I figure it could be done using Pass-Through authentication.

For this, I need to create /usr/lib/sasl2/slapd.conf

And adding a few config paremeters. This is a example

mech_list: plain pwcheck_method: saslauthd saslauthd_path: /var/run/sasl2/mux

I understand the mech_list parameter, but I have no Idea what to put in for the rest. Any help?

Thanks! Nathan
