Hi Folks, looking for some feedback on an issue I've been dealing with as of late.
Issue:
Device X connects to SSID: xxyy. MAB authentication, Redirect to CWA, CWA responds with [500] Internal Error. Please contact system Administrator. If you are the System Administrator please consult the logs.
Device X connect to SSID: yyxx on same AP associated to same WLC. MAB authentication, Redirect to CWA, CWA login page pops, no error.
Troubleshooting:
PSN rebooted - Sometimes resolves the error. Does come back.
Device purge
Live authentications shows device stuck in RADIUS Accounting start request with no Auth Method. Forcing the device to Reauth via CoA from live authentication view triggers the device to Authenticate, Auth Method show mab and device is presented with CWA page.
Only log I found associated to the device
-::90:B6:::ProfilerCoA:- In DAO getRepository method for HostConfig Type: MNT

Resolution to anyone having these symptoms.
If you have a WLC that has an anchor point, only enable Accounting on one WLC. Having Accounting enable on both WLC causes Accounting information to be sent twice to ISE. ISE will invalidate one of the sessions upon reception of the second and cause the client to produce 500 Internal Error.
