Reject packet with zero length

[muralidhar.gangaraju]

Hi all,               We are using FreeRADIUS server for one of our requirements and we saw freeradius server sending a reject packet with zero length attributes.             Could anybody of u can help me in understanding in what circumstances FreeRadius server will send a reject packet with zero length attributes in between the access challenges OR access requests. In the normal scenario when the password or certificate mismatch is found the FreeRADIUS sends an access-Reject packet with EAP-Message and message Authenticator. But in the below case it does not send any attributes.               One such instance where we observed radius server sending reject packet with zero attributes is as follows.   Going to the next request Cleaning up request 17 ID 243 with timestamp 44dd6e90 Waking up in 1 seconds... --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Sending Access-Reject of id 246 to 10.201.114.29:1050 Waking up in 4 seconds... rad_recv: Access-Request packet from host 10.201.114.29:1050, id=165, length=158         NAS-IP-Address = 10.201.114.147         NAS-Port = 2         Framed-MTU = 1388         NAS-Port-Type = Wireless-802.11         Service-Type = 128         Called-Station-Id = "60-c4-b6-48-80-00:"         Calling-Station-Id = "fc-50-d1-ba-70-00"         NAS-Port-Id = "fc-50-d1-ba-70-00"         State = 0xe92296731885b23183f47834fb748272         User-Name = "root"         EAP-Message = 0x020500060d00         Message-Authenticator = 0x035037019647238daa63c6f29829afd2   Processing the authorize section of radiusd.conf modcall: entering group authorize for request 20   modcall[authorize]: module "preprocess" returns ok for request 20   modcall[authorize]: module "chap" returns noop for request 20   modcall[authorize]: module "mschap" returns noop for request 20     rlm_realm: No '@' in User-Name = "root", looking up realm NULL     rlm_realm: No such realm "NULL"   Please let me know if u need any more information.   Thanks in advance.   Regards, G Muralidhar Raju.
