Hello everyone,
with the sunset of multiple services in MacOS server, we started to look for an alternative of our mail service. Since we prefer to maintain our Apple's Open Directory for user management, I am looking for some guidance on how to setup user authentication in iRedMail from an external Open Directory.

Any hint, would be appreciated.
