I discribe my config and maybe there is something wrong somewhere.
In QEMC under System - Setup - DSC I config Active Directory (ADDOMAIN-NAME) without Autentification, the same for Windows NT (NTDOMAIN-NAME). No config Custom or Local Directory. I did it via "GetDefault" button.
In QMC I can see all my document under User Documents. In Authorization I add reciptients (NTDOMAIN-NAME\group_name or group_name@ADDOMAIN-NAME)
