moby: Windows Server Container: System.DirectoryServices.AccountManagement.UserPrincipal not working

The FindByIdentity method on the System.DirectoryServices.AccountManagement.UserPrincipal object does not work inside a Windows Server Container. It throws an exception stating that the Server service is not started. Trying to start it also fails with an exception. See reproduction details below.

Is this a bug in the Windows Server 2016 Container feature or is this part of the .Net Framework not supported?

Steps to reproduce the issue:

1. clone https://github.com/martinh2011/uperrorrepro
2. docker build -t uperrorrepro
3. docker run -it uperrorrepro

Describe the results you received: The System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity API call throws an exception

Describe the results you expected: The System.DirectoryServices.AccountManagement.UserPrincipal.FindByIdentity API returns a UserPrincipal object

Additional information you deem important (e.g. issue happens only occasionally): If you do the same API call on a plain Windows Server 2016 Core, i.e. not inside a container this works. Trying to start the server service like this:

1. docker run -it microsoft/windowsservercore powershell.exe
2. In powershell inside the container: start-service server

fails with

Failed to start service ‘server (lanmanserver’ Eventlog does not have anything useful, just

The Server service terminated with the following error: %%2
