Welcome to Rockstor @rakey. So AD integration has been volatile and some new changes are about to be pushed in next couple of testing updates. You’ll see from our wiki post that the current approach uses SSSD and it’s been problematic for a couple of reasons. We’ll be moving to a winbind approach (may still offer sssd approach as an option in the future) in this dev cycle itself. So, my recommendation to you is stay tuned for announcements in the next week or so for more information. You’ll be able to test it very soon.
