Hello all! I'm seeking to achieve a multi-domain setup with Cyrus-SASL, postfix, Cyrus-IMAP and LDAP as the backend.
In general I think it should be possible to have completely separate user spaces (defined as separate but similarly-formed branches of the LDAP tree) and have that work with SASL (via saslauthd with the LDAP plugin). My idea is to have "multiple" postfix "instances" (for all intents and purposes that's what they would be) processing e-mail for a single domain each, delivering to the corresponding cyrus-imap instance (I followed a howto @ http://www.phildev.net/cyrus/cyrus_sasl.html which allows me to do just this with Cyrus-IMAP). However I have some issues to resolve before I can implement and test this setup: How do I tell saslauthd how to find the user list for a particular realm? Since both postfix and Cyrus-IMAP can specify to SASL which realm the user is being authenticated on, all I should need is to define where/how each realm's users are accessible, right? A side question: assuming such a setup is successful, would creating a user in LDAP be enough for that user to be able to retrieve e-mail, or would I additionally have to use cyradm to create the mailbox (i.e., would Cyrus-IMAP recognize that the mailbox isn't there and create it automagically?). Assume that for each postfix/cyrus-imap combo there would be a different IP address through which they'd be accessible (this is required to do the multi-domain setup with cyrus-imap).
