Welcome to the Centrify community.
A general framework to troubleshoot group policy:
- Make sure the GPO applies to the system in question. (in AD)
(e.g. use GPMC resultant set of policies) - Run adgpupdate and then verify with adgpresult. (in Managed client)
- If you don't get the GPO, repeat step 1 and also verify communications over SMB
e.g. adinfo -T [domain controller name] or adsmb tool.
