Hi, I stumbled upon a strange behaviour of my switches. I want to configure 802.1x. In the first packet the Switch sends: Debug: (7) Received Access-Request Id 81 from x.x.x.46:36296 to x.x.x.154:1812 length 152 Debug: (7) User-Name = "3464A9D11215" The debug goes on: Debug: (7) eap: Peer sent packet with method EAP Identity (1) Debug: (7) eap: EAP session adding &reply:State = 0x45e56b9d45e46617 Debug: (7) modsingle[authenticate]: returned from eap (rlm_eap) Debug: (7) [eap] = handled The next request from the switch is: Debug: (8) Received Access-Request Id 82 from x.x.x.46:36296 to x.x.x.154:1812 length 167 Debug: (8) User-Name = "host/test@xxx.xx" (...) Debug: (8) State = 0x45e56b9d45e46617718e28efb749ef6f and then the RADIUS server complains: Debug: (8) eap: Previous EAP request found for state 0x45e56b9d45e46617, released from the list Debug: (8) eap: Identity does not match User-Name. Authentication failed Debug: (8) eap: Failed in handler Can anyone explain what happens here? Does the switch change the User-Name within the RADIUS / EAP session? Is this a bug of the switch? Or does something other happen here? Thanks for any hints.
