Hi, I would like to know what does the attribute PW_DIGEST_NONCE (1064) represent in rlm_digest module in radius server? My radius log information is given here. <------the radius log information for the authentication packet starts here----------> Received radius packet: NAS-Identifier = "localhost.localdomain" Digest-Attributes = "\003\010INVITE" Digest-Attributes = "\006\005MD5" Digest-Attributes = "\002*60d9d2b7b8ab7b4da4014bcdac1724b7320068d6" Digest-Attributes = "\n\0146599999970" User-Name = "6599999970@192.168.104.239" Digest-Attributes = "\004 sip:6599999508@192.168.104.240" Digest-Response = "1ee3c49572b6fcd4a9e0438bba8810dc" Digest-Attributes = "\001\021192.168.104.239" rlm_sql in rlm_sql_authenticate <------the radius log information ends here----------> The Digest-Attributes = "\002*60d9d2b7b8ab7b4da4014bcdac1724b7320068d6" is the PW_DIGEST_NONCE with 60d9d2b7b8ab7b4da4014bcdac1724b7320068d6 as the value. In my setup, the radius client uses SIP. I want to know whether the PW_DIGEST_NONCE in the digest attributes can be used as a Session ID of the SIP call or the Call-Reference of the authentication packet? Or, only after receiving the RLM_MODULE_OK for the digest request, the radius client will send the further SIP call information in the next packet? A little background about the problem I face: I have a customized radius source(taken from freeradius few years back) to work with radius clients to perform authentication and accounting with only rlm_detail, rlm_preprocess, rlm_sql (with unixodbc) modules. Now, I have a requirement for the radius server to work with a radius client which has SIP. And I have found that radius client with SIP uses 'rlm_digest' module as part of authentication. This is when I have the following issues: a) I can not just integrate 'rlm_digest' module source to the existing radius server source to work since the changes are quite a lot. b)I have very limited or no details about how the radius client with the SIP works. This is why I wanted to get more information about the role of rlm_digest module and how to handle it in my situation.
