ArcGIS Server user account options.

[ErinAtkinson]

Currently you can configure AGS to manage users with the built in Identity Store or Active Directory.  When using Active Directory you are limited to a single domain.  I would like to see these additions made to the ArcGIS Server user account options:
1. Support multiple domains when using active directory
2. Support using active directory and the identity store at the same time

Thanks for this excellent idea.  Even the ability to choose an AD domain instead of just the default would be useful.

This is now possible in ArcGIS Enterprise.
