KB-18611: Unable to Login to Linux Client After Domain Controller Upgrade to Windows Server 2019

Authentication Service ,  

12 August,19 at 05:07 PM

Problem: After upgrading a domain controller to Windows Server 2019, it has been reported that Active Directory users can no longer login to Linux clients with Centrify Direct Control (adclient) installed. There may also be issues with adjoin due to this. Why does this happen?



Cause: Centrify adclient is expecting a response from a domain controller that includes the "netlogon" attribute. However, starting with Windows Server 2019, the domain controllers will return a "NetLogon" attribute. Notice the change in case between netlogon and NetLogon.


In the adclient debug logs, there should be a line that looks like below:

adclient[64695]: DEBUG <bg:ageBindings> util.except (System) : ADAttribute 'netlogon' is empty (reference lrpc/adobject.cpp:73 rc: 1)




Solution: This has been fixed in our Centrify Direct Control agent version 5.5.2 (Centrify Infrastructure Services 18.11 release). Please upgrade to 5.5.2 or higher.
