dovecot - Jan 2009 - 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

Now you're talking about using Cyrus SASL, not Dovecot SASL. Dovecot
doesn't use such a file.

Well, I have to admit, I do not know what I am saying.

I wanted to authenticate in openldap using dovecot-sasl. The only useable thing
I could find was this document describing pass-through authentication. And it
talked about the /usr/lib/sasl2/slapd.conf. It belongs to cyrus sasl? Mmh ...

Does anyboday know if and how openldap authentication using dovecot is possible?

Thanks!
Nathan
