<p class="MsoNormal"><span style="color:#1F497D">In IPP the destinations for fax/scan are handled the same way sources are handled for print by reference. Authentication credentials of the user are not given to the IPP Printer/FaxOut/Scanner to gain access.
AAA of the referenced document/destination is not incorporated into the protocol or model. Based on market and customer requirements the appropriate security scheme is used in the implementation. The IPP specification does not dictate the required security
model. For example the destination could be public or restricted to only allowing write access by the scan service. Other alternatives include the inclusion of access tokens in the URL as is used with OAUTH’s Resource Owner Credentials Grant. One of the
reasons for the “destination-uri-ready” was to assist the user in a secure environment determine the destinations available for the deployment. As with any IPP attributes the values returned by the Server can be filtered based on the Client’s current role.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">May I know how PWG solves supporting IPP destinations (and other HTTP destinations) that need authentication when used as a destination in FaxOut/Scan2 defined workflows?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Are authentication information for URIs under destination-uri-ready (implicitly) managed by the MFD as it appears that the specification does not provide any destination specific attributes in the destination-uri
collection to provide authentication credentials? Or should authentication information be provided in the URI as it is done for some http URI allows like
<a href="http://user:passwd@mystoragedrive.com/folder">http://user:passwd@mystoragedrive.com/folder</a>? If so, I would wonder about IPP destinations and ipp/ipps URIs.<o:p></o:p></span></p>

<p class="MsoNormal">We should just include Job Template attributes directly in the destination-uris and destination-uri-ready collections. Thus, it would just be:<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This would be consistent with how other attributes (job-sheets-col, covers, etc.) deal with embedding Job Template attributes in collection attributes.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">If you really want to put the Job Template attributes in their own collection, call it "destination-attributes"; we never use "collection" spelled out in the name, and generally only add -col if there is already a non-collection form of
the attribute (e.g. media and media-col, finishings and finishings-col, etc.)<o:p></o:p></p>
