Applies to: All versions of Centrify Connector 

Problem:

The connector registration is failed with a message asking to login with user from AD forest:

Please login with user from AD forest xxx.xxx.


Cause:

Centrify Connector will verify the currently login user's forest and see if it differs from the computer joined forest. The cross forest user is not allowed to register the connector service in local forest. 
 

Use this powershell command to check current user's forest:
[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest() 

Use this powershell command to check current computer's forest:[System.DirectoryServices.ActiveDirectory.Domain]::GetComputerDomain() 

Below connector log will be seen and it can be used to find out which forest the user and connector machine belong to:

Resolution:

Login the connector host with the local forest's user.
