Doing a wired setup, all done with downloadable user roles from Clearpass.
Now arrived at the wired guest (captive portal) part.
Using DUR to return the initial logon-role works, but then..
Is it possible to use DUR in a CoA? Is there another way to keep my DUR? Or does my entire single point of user-role config fall apart here?
