Hi. In ArcGIS Online, is there any way to add enterprise accounts automatically? We use Active Directory. Currently, we invite users individually. It works, but often causes users some frustration, as the sign in interface is confusing and unless they follow directions well (which they don't), they end up doing it wrong, frustrated and with a bad first impression of AGOL. It is also problematic because we often need to add them to a particular group, once they have accepted the invite, but this requires them to notify us once they have done so and they may or may not do that. Better if admin can add them automatically and then configure group membership right away. Our current option to invite users is the fourth one in the list "Invite members to join using their enterprise logins".
So, best option would be providing an AD security group, and adding all members automatically, but we would be fine with providing a spreadsheet if that is an option.
Second part - if not possible in AGOL, is this possible with Portal? We are considering whether to deploy portal or stick with AGOL for various reasons and this would help us decide.
