Question

Cisco WLC Error Message - Clients Stuck on "Validating Identity" After Working for a While

Asked by: kaos_theory

System: Windows XP SP 2 client, domain joined
Authentication through RADIUS server

Error on WLC: Received EAPOL-key message while in invalid state (0)

On Client:  Works for a while, then gets stuck at "Validating Identity", and the icon flickers with a red Question Mark constantly

On RADIUS:  When IAS logging is turned on, the log file jumps in size very quickly, approx 8MB a minute, filled with the same message over and over:  <IP of WLC>,<Domain\Username>,03/12/2008,14:14:37,IAS,<name of RADIUS svr>,4128,wireless lan controller,25,311 1 <IP of RADIUS Svr>11/21/2007 15:29:44 30354085,4132,Secured password (EAP-MSCHAP v2),4127,11,8100,1,4130,0x4947454E2E4C4F43414C2F2142657468657364612F55736572732F4C6F6773646F6E2C2044656C656E61,4294967206,0,4294967207,1,4108,<IP of WLC>,4116,0,4155,1,4154,Use Windows authentication for all users,4129,<Domain\Username>,4149,authenticate wireless lan users with PEAP,4136,2,4142,0

While in this state, other issues might occur on the client, such as:

Typing "ipconfig" results in an error message that crashes the DOS window (don't have the error off the top of my head).

Rebooting the workstation resolves the issue temporarily.  Then the cycle begins anew.
