Hello, Robertson
I have tried with Direct manage 5.5.0 but the problem is the samne. There is authentication failure of AD users, sometime the login is successfull some times login will fail.
There is a problem with latest Ubuntu 18.04 gdm3 or is a problem with direct manage 5.5.0 version because there is no problem found in login with local user of Ubuntu 18.04.
Do you have any solution for that, I think Centrify already tested Ubuntu 18.04 before launching the direct manage 5.5.0 for latest OS releases.
