Summary:
The document is almost ready for publication as a standard track RFC

Major issues:

Minor issues:

1. In section 2.4 " If the UAC cannot respond to any of the challenges in the
response, then it SHOULD abandon attempts to send the request, e.g. if the UAC
   does not have credentials or has stale credentials for any of the realms,
   unless a local policy dictates otherwise." Yet RFC3261 section 22.2 " If no
   credentials for a realm can be located, UACs MAY attempt to retry the
   request with a username of "anonymous" and no password (a  password of "").
   Is this deprecated ?

 

No, it is not deprecated by this document, and that part is covered by the last sentence of the quoted paragraph, which talks about a local policy.

 

RE: I have no strong feeling it is just that the language is different

 

 

2. RFC3261 algorithm includes "MD5-sess" while section 2.6 removed it

 

These changes are provided in the context of RFC7616, so if an implementation supports "-sess" it could always refer to that document for these details.

 

RE: I think that the BNF

algorithm = "algorithm" EQUAL ( "MD5" / "SHA-512-256" / "SHA-256"/ token ) 

should be 

algorithm = "algorithm" EQUAL ( "MD5" / "MD5-sess / "SHA-512-256" / "SHA-256"/ token )

 

 

3. it may be good to have a backward compatibility section.

I believe we covered that in the security consideration section. Do you see anything missing there?

 

RE: OK, no problem.
