I have been using basic authentication via an Apache Kerberos module for sometime. It authenticates users to an Active Directory DC. I have installed this plugin to integrate WordPress authentication.
REMOTE_USER variable is set to username@OUR.DOMAIN and so no match occurs. I am not able to create usernames in the that format since WordPress allows only lower case and no @ symbols.
To the best of my knowledge, although it has been a few years since I set it up, there is no way to change the REMOTE_USER value to strip the @DOMAIN part (which I am assuming is the problem).
How can I integrate these two systems?
