I am trying to connect from Trados Studio 2022 Professional (17.2.10.19084) to Groupshare server (Groupshare 2020 SR1 CU13) with Windows user so that this Windows user belongs to different Active Directory than Groupshare server. Services are running under service account that should be enabled for both ADs. But I get following error in Trados Studio:

SDL.ApiClientSDK.GS.UserManagementV2Client - Server returned unsuccessfull status code : Unauthorized, Message : StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: <null>, Headers:
{
} Exception TraceId :
FATAL [2025-11-24 10:52:16,508] Sdl.Desktop.Platform.UnhandledException - One or more errors occurred.
System.AggregateException: One or more errors occurred. ---> SDL.ApiClientSDK.GS.Exceptions.NoPermissionException: Server responded with Unauthorized while trying to make a "GET" REQUEST at Url: "">_groupshare_server_url_/.../users.

Full response content: Response status code does not indicate success: 401 (Unauthorized).Content: StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: <null>, Headers:

} 

User "AD\uid" is configured in Groupshare console as a Windows user.

Is there necessary any other configuration?

Thank you.
