As far as I understand it, this 'error' happens when libsasl in slapd tries to intialize all plugins it can find, when it intializes itself. It runs over the ldapdb plugin, the plugin replies "I need ldapdb_uri", and libsasl returns "invalid parameter" allthough ldapdb is never being used for slapd.conf. I do have slapd.conf though to limit the mechanisms as I don't have Kerberos and want to use shared-secret mechs instead. > >>>The OpenLDAP slaptest utility didn't report any errors on slapd.conf. > >>>Also the log_level I've set in /usr/lib/sasl2/sample.conf didn't give me > >>>any verbose output either when I used Cyrus SASL's server and client to > >>>test authentication. > >>> > >>>Any hints or ideas? > >> > >>What are the contents of sample.conf?

I am a little bit further, but not done all the way (which is why it took me some time before I started to reply to your mail). It turns out my mapping for the proxyuser in slapd.conf had been incorrect and the whole process of authorization and authentication didn't work from the very beginning. Additionally I had the authzTo attribute placed wrong... Anyway, basic functionality is there now. There's still something that doesn't work. I can authenticate users from ou=purchasing,ou=people,dc=example,dc=com, but not from ou=it,ou=people,dc=example,dc=com, which really drives me crazy at the moment, because I don't understand it, but this is a problem I will probably take to the OpenLDAP mailing list. Thanks for the assistance so far! p@rick -- The Book of Postfix <http://www.postfix-book.com> saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>
