Hello,

Recently, when reviewing the "Get-User-Printer-Attributes" white paper internally, I got asked a bunch of questions about how IPP works with different HTTP authentication / authorization models. I don't have a deep knowledge of this space, but I thought it was something that was important to document. I created sequence diagrams for a number of different HTTP authentication / authorization schemes and how I imagined IPP would fit into this. I have uploaded a PDF with these sequence diagrams for review by the IPP WG:

http://ftp.pwg.org/pub/pwg/ipp/whitepaper/ipp-authentication.pdf <http://ftp.pwg.org/pub/pwg/ipp/whitepaper/ipp-authentication.pdf> 

Any feedback? Should we perhaps make a new white paper / technical brief that incorporates approved versions of these to document this increasingly important aspect of IPP Client / Printer interaction? In particular I don't know if I got the OAuth2 portion correct.

Smith
