Hi all, I've one question regarding the draft 'korhonen-dime-pmip6-03.txt' (http://tools.ietf.org/id/draft-korhonen-dime-pmip6-03.txt). If the MAG performs a user-authentication toward the HAAA server, it uses the User-Name AVP to identify the MN. After a successful authentication the HAAA server replies with a Chargeable-User-Identity. My question: Should the MAG use the Chargeable-User-Identity for the PBU and its MN-ID option, or should the MAG use the content of the User-Name AVP as MN-ID option in the PBU? Section 6.2 on page 14 says that the User-Name AVP must contain the MN identity if the LMA sends a Diameter message toward the HAAA server. The value for the User-Name AVP the LMA has extracted from the received PBU (MN-ID option). In my view it isn't clear if the User-Name AVP toward the HAAA server should contain the Chargeable-User-ID AVP content to authorize the PBU, or if the AA-Request and its User-Name AVP contains the NAI, which was initially used to authenticate the MN by the MAG? If the User-Name AVP toward the HAA server contains the Chargeable-User-ID AVP content, then the real identity of the MN can be concealed from the LMA, but the HAAA server is able to identify the real identity of MN, as it has assigned the Chargeable User-ID. I hope, you can provide me with some information on this matter. Thanks you in advance Rafael _______________________________________________ DiME mailing list DiME@ietf.org https://www.ietf.org/mailman/listinfo/dime
