You need to make sure you have the correct schema's loaded by slapd more than likely the ones you'll need are: core.schema, cosine.schema and misc.schema. I'm not sure if IMAP requires something that other mail protocols don't though.. NOTE: these schema's are provided with slapd on debian I don't know about the source distrobution or RPMs. Try these places for more info: http://www.linc-dev.com/auth.html http://www.imap.org/ This one's very wordy but may be valuable: http://www.georgetown.edu/giia/internet2/ldap-recipe/ Hope this helps. * Blake -----Original Message----- From: dino bartolome [mailto:dino@pobox.com] Sent: Tuesday, June 05, 2001 1:39 PM To: pam-list@redhat.com Subject: pam and openldap I am trying to authenticate my courier imap server to authenticate like this: pam -> ldap however imap servers require more user information like location of maildir etc.. this user information will be stored in attributes for each entry..... how would i retrieve this information using pam? or in other words how could courier retrieve this information from pam and pam retrieve this information from openldap?
