one user can connect only upto to two wireless machines(2504 WLC issue)

Hi Everyone,

I am having issue with my 2504 WLC. I have SSID Corp with 802.1x configured on controller which is working with NPS server for user authentication. I recently found that one user can only connect to two wireless machines if he try to connect with third machine then login fails. NPS logs show that access granted. NPS allow access. On WLC clients entry i can see only two user connected when third try it shows blank entry and no connection. 

We can connect to iPhone, Mac or Windows. Only two then third machine never join. I have to disconnect one of first one to join that third machine,

i did debug and here is error..

same user can connect to 10 machines at same time over wire.. I dont believe so there is issue with NPS.

Hey this issue has been fixed, there was secutry option on WLC

WLC and go to Security > User Login Policies and change the value for “Max Concurrent Logins for a user name” to 0?

Before there were only 2 user allowed.

Hi, Tarjeet.

Your answer is correct, I solved my same issue to change this value from 2 to 8.

Regards.
