I am one of a few Administrators on a portal. The portal has been set up with Integrated Windows Authentication (IWA) so that Active Directory (AD) groups can be linked to Portal for ArcGIS.
One of my fellow administrators created a new group and associated it with Users from an Enterprise Group using AD. I am a member of this particular Enterprise Group in AD, however when I log into portal using my administrator privileges and click 'Groups', I am not recognised as a member of this group. We double checked AD and I am definitely a member of the associated group.
What might be causing this issue?
