I appreciate the help, but I am indeed looking at the User Column.    It appears for one reason or another that I am seeing clients in the Meraki dashboard even though they are being denied access to the wifi. I took my cell phone over to the building where the user is appearing and I tried to access the wifi using the user in questions credentials. I got a message saying there was a problem connecting and it would not let me on the network. When I got back to the office, I see the username in question associated with the mac of my cell phone. It showed that only 2kb of traffic had been used by the device. My guess is that during the RADIUS hand shake the clients are momentarily added to the network, and then denied access if they don't match any of my NPS rules.  ... View more

I believe it is another user using the original users credentials. We only allow a small number of students access to the specific wifi SSID. They must have an accommodation to be granted access. I noticed the issue because there was a high number of students on the SSID in question. When I looked up this particular student in AD I was unable to locate their account. I did a search using powershell as well as ADUC. I found the student in our student information system, he graduated last year, but our SIS is in no way tied to AD.    I went over to the school and tried to authenticate to the wifi with my cell phone and I was blocked. When I look in the Meraki dashboard at the clients page I see my phone with the students name, and it only shows 6kb of usage. Maybe I am interpreting the dashboard incorrectly, I thought it would only show me users that are actually authenticated.     ... View more
