Configuring MSAD in RHEL

We are trying to configure MSAD in our LINUX VM(RHEL).So that users can login with there accounts directly to the LINUX VM(RHEL) instead of using service accounts.Can someone help me out here ?

Thanks

What version of RHEL?

If RHEL 7, man realm.

On RHEL 6, there is a menu under Administration -> Authentication. I usually use winbind.

Red Hat Enterprise Linux Server release 6.5 (Santiago)
