Hi Pete,<br><br>That proxy via the same directory service in the same security domain<br>under a TLS tunnel is one thing.<br><br>But how do you propose that it could possibly apply in the case that<br>one or more Cloud providers and and an entirely different target domain<br>
all participate to print the original client's job - letting that original client<br>directly cancel jobs on those downstream printers is going to cause real<br>headaches of accounting and security.<br><br>Cheers,<br>

All that is required in a fan out environment is the child trust the parent. If it is a secure system it certainly won’t depend on the “requesting-user-name” and it will have a special administrative role assigned to the parent printer. The initial printer can authenticate the client. If access is permitted at the target printer then the target printer has to tie into the same authorization domain as the initial printer.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">The semantics are limited to Job forwarding systems of printers (i.e. IPP Fan out and fan in). On the first system the Job’s “original-job-requesting-user-name” and “job-originating-user-name” are populated with the same value. Per rfc2911 that value is the most authenticated printable name that it can obtain from the authentication service over which the IPP operation was received. Only if such is not available, does the Printer object use the value supplied by the client in the "requesting-user-name". On the next hop is where things diverge. The upstream printer uses its own identity in the “requesting-user-name” operational attribute. It also passes along the “original-requesting-user-name” as an operational attribute. The downstream printer uses the “requesting-user-name”, or the identity obtained from a trusted protocol layer, to insure the request is from a configured upstream printer. The downstream printer then copies over the “original-job-requesting-user-name” operational attribute to the job object AND to the job object’s “job-originating-user-name”. In other words the child job is owned by the initial submitting user throughout the chain and not by the immediate parent (i.e. IPP Printers).</span><u></u><u></u></p>
