Can Active Directory Groups be used to assign concurrent licensing in an Option File? Or must individual NetworkIDs be listed?
You may want to Move this question to https://community.esri.com/groups/arcgis-for-desktop-installation-support?sr=search&searchId=50e8b55... which is a better place for licensing questions.
I don't know the answer for sure, but my guess is it will not take AD groups.The option file isn't the most powerful or reliable. I have always found it to be easier to block a user totally that grant something to an individual or group. fwiw.
