Hi all, Just wondering whether somebody's having a setup where authentication is required for relay access with an extra authorization check. Summerizing:
1. User wants to send a mail to postfix which needs to be relayed 2. So, user identifies him/herself to postfix and authenticates 3. After that, postfix looks up the ID (used in step 2) in a list of authorized users and if found, finally gives access. For authentication I've successfully implemented GSSAPI (for SSO) and as fallback Kerberos via saslauthd. Even multi-realm authentication works. For authorization I'm looking for something that does an LDAP lookup. Till now, I couldn't find a way to implement this. Which doesn't mean it's impossible... Any ideas/suggestions would be much appreciated! Durk
