Next Active Directory Integration

I had some issues finding out how to configure it correctly. I usually login with "INTERN\john.doe", but a format like this was not valid. I found out that I had to use "john.doe@intern.example.com" and to add the two suffixes "@intern.example.com" as well as "@example.com". I activated the automatic user creation and all worked easily. Awesome work!

Once you figure out your configuration, it work perfectly!

Next Active Directory Integration allows WordPress to authenticate, authorize, create and update users against Microsoft Active Directory.
