Windows Admin Center version 2410 is now in Public Preview!

When will WAC support Active Directory again?

It doesn't appear to allow two key features:

1) Using Domain groups for membership

Couldn't add security group Access Members in the preview version?

Type: Error

Message: Error: System.DirectoryServices.Protocols is not supported on this platform.
I haven't found any matching documentation? Any reference to directory services/Active Directory integration is missing?

2) Adding/searching the domain for computers to add?

Search Active Directory

• We can’t search Active Directory because the Windows Admin Center computer isn’t joined to an Active Directory domain. It’s also possible that your account doesn’t have permission to read from Active Directory.​

I have redeployed different versions of WAC preview about once per month since January and still this same problem?
