WLC 7.0.220 - USER_ADD_FAILED

[Hosam Badreldin]

Here is what I'm getting:

*Dot1x_NW_MsgTask_0: Apr 16 10:08:53.443: %APF-1-USER_ADD_FAILED: apf_ms.c:5665 Unable to create username mag12 for mobile00:21:5f:b2:f6:87.

I have WPA2 with 802.1X ties back to ACS 5.3. Works great, but I got a client having a problem today. Cisco doesn't say much about this error and it consider it an internal error? How to fix it? what does it mean exactly? Anybody?

Here is my CLI debug output last few lines:

Looks like there may be a stuck/stale entry in the MSCB that is not allowing that client to be added.

You could try rebooting the WLC to see if it clears it.

There is noway we can clear the MCSB entry table for that controller from command line? The user is able to authenticate from time to time so it is an intermittent issue.
