We have an intermittent LWAPP LEAP authentication problem. Does any of\nthe errors below ring any bells with anyone? The application is Vocera\n(VOIP) authenticating using LEAP. Below is a summary.\n===============================================================================\nThe ACS DLL error is a new one, I think it might be the key. Same\nstory, it starts and doesn't stop and all the controllers report the\nsame error.\n================================================================================\n Here is the error that is occurring on the Controller.\n\n Tue Aug 28 14:17:24 2007\n RADIUS server 10.64.2.20:1812 failed to respond to request (ID 125)\nfor client 00:09:ef:02:5f:73 / user 'unknown'\n\n Tue Aug 28 14:17:24 2007\n RADIUS server 10.64.2.20:1812 failed to respond to request (ID 124)\nfor client 00:09:ef:02:67:db / user 'unknown'\n=================================================================================\n\nHere is the error we see in the ACS error logs.\n\n08/28/2007 14:03:40 Authen failed xxxxxx BHS_WAP 00-09-EF-02-63-5E\n(Default) Radius extension DLL rejected user\n================================================================================\nHere is an explaination of the error.\n\nRADIUS Extension DLL Rejected User Error\n\nCondition\n\nLEAP authentication fails. The error Radius extension DLL rejected\nuser appears in the Failed Attempts log.\n\nAction\n\nTo verify configured authentication type:\n\n-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\n\nStep 1 Verify that the correct authentication type has been set on the\nAccess Point. Be certain that, at a minimum, you checked the Network-\nEAP check box.\n\nStep 2 If you are using an external user database for authentication,\nverify that ACS supports the database. For information on the external\ndatabases that ACS supports, see User Databases, in the User Guide for\nCisco Secure Access Control Server.\n=================================================================================\n\nDoes this ring any bells? Are we missing an obvious setting?
