Since I received valuable non-editorial feedback in addition to editorial feedback on the draft from the PWG Last Call, I have produced a new revision that hopefully resolves all the issues and can be used in a second last call.

In the context of GDPR, this falls under a need for explicit consent - a password challenge or Client UI requesting permission to provide the real user name is required. At Apple we decided to always hide the requesting user on iOS for basic privacy reasons, relying on authentication where such information is genuinely needed.</div></div></blockquote><div class=""><br class=""></div>Do you want this in section 4.2 "The 'requesting-user-name' IPP Authentication Method" (using numbering from the non-rev documents), or in 5.1.1. "General Recommendations" (for Clients), or 7.2. "Client Security Considerations"? There seems to be two different statements: what is done in the field, and what a Client or Printer ought to do.</div></div></blockquote><div><br class=""></div>I was thinking of this being in section 4.2. As far as the general recommendations for clients, I think we need to make a note of privacy concerns, .i.e., recommend that Clients don't just throw the current username in there without getting explicit permission from the User.</div><div><br class=""><blockquote type="cite" class=""><div class=""><div style="caret-color: rgb(0, 0, 0); font-family: Menlo-Regular; font-size: 11px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><blockquote type="cite" class=""><div class=""><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;">In the general client recommendations (section 14.2?), you say:</div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"> Client security considerations (section 18.2) should also be followed.</div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;">Since we have a lowercase "should" here, perhaps reword this as:</div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"> Also see section 18.2 for Client security considerations and recommendations.<br class=""></div></div></blockquote><div class=""><br class=""></div>OK.
