Hi,
I just noticed that any administrator role in ISE 2.6 is able to change his/her own login name via the Account Settings in the top right corner.
Is there a way to disable this behavior? So far I couldn't find an option in the admin settings.
EDIT: Just saw in the documentation that this should only be able for Super and System Admins. I just tested it successfully with the role of Helpdesk Admin
