we've ISE 2.7 patch 2 and Super Admin Access is authenticated by a AD-Group (external Identity Store), this works without problem.
We've another Admin Group for an internal user-store, and this group is authenticated also external by another group on AD.
They login very rarely, but now they can't login anymore (invalid username or password)
They use this accounts for there daily work, so the accounts are ok
if I try to change the mapped group to a group where I'm member of, it works neither.
Under the AD connector the groups are fine, I can retrieve ssid or attributes.
The same occurs on a standalone ISE and on a Deployment (same Patch-Level)
Any Idea, where I can start the search?
