i have a user who is getting the following pop up window with message, " additional log on information may be required". This is a windows7 laptop connecting to the 802.11 wireless network using eap-tls. When i look at the authentication logs on the AAA server, it shows a successful authentication. This does not affect end user performance, instead it's just an irritating popup.
Through a google search I came across a thread related to "openDNS", however when i opened up a ticket with them they said openDNS could not be causing this issue.
I would like to know whats causing this pop-up and how to eliminate? Please see attached photo of pop-up.
