In this afternoon, I did some testing in WLC in our company wireless network.
However, after my 3 hours testing, I had tried to login WLC again by GUI and SSH. The admin username and password does not work any more. All Read only and Guest Account did not work as well.
Is any one had this issue before? Is there a restriction for access to WCL per 3 hours or one day? By the way, I did not change any password.
No problem... glad I can help! One thing to do next time when you are testing radius, is to open up another browser that is logged on. This way when you logout of one browser to test authentication and get locked out, you can go to the other browser to make a change. Just make sure you use a different browser of machine. Not a new tab... does not always work well with tabs:)
You need to make sure the wlc can't communicate to the radius servers, then the priority will try the local account. So you either take down the radius servers or you disconnect the wlc from the network and then use the service port or console to access the wlc. It will work, since now we know that the priority was set to radius then local. You could setup an acl to block connectivity if you want, but unplugging the wlc from the network is easier.

Well.... something changed on the WLC for that to happen. What were you testing? Changes in your radius setup and enabling management or the priority order can cause you an issue if things are not setup right. If that is the case, dissconnect the WLC from the network and connect to your service port or console port and login.
If you can't log on, here is a link for how to do a password recovery on the WLC:
