Hi,

I want to thank you for this product. It is very good and the integrations too.

I have one question - is it possible and how to use the freshly installed iRedMail with ldap like AD service, to join computers in domain, central authentication, authenticate servers and services.

The idea is to use the system not only as a mail service, but as an active directory service, without loosing the mail server/services features.

Thanks in advance.
