AD Accounts Not Logging In

I know this has been an issue for quite some time with AD accounts that authenticate with Centrify on a Mac with FileVault enabled not being able to log in under High Sierra. This is really starting to affect my job and was wondering if there was a fix? The reason I ask is it is happening to me and a few very important coworkers at my company. I upgraded my Mac to Mojave with Centrify version 5.5 but still issue remains. Any ideas or suggestions on how to solve this? I am getting desperate. Thanks for your help.
