<p class="MsoNormal"><span lang="EN-US">>When you describe it that way, that sounds like the canonical use case for SAML delegation, described here:<br>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri Light",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Thanks for your input Bret. I agree with you, the way I understand my problem really sounds like the SAML delegation
use case. If I was under control of the AWS SP I would take this route. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">>However, in your initial description it sounded like the AWS consumer wasn't exactly an SP implementing the Web >Browser SSO Profile. If it wants you to obtain (somehow, in an unspecified way) an Assertion targeted
to it and then >pass it in a proprietary API call, etc, to establish a session or security context, then that's not really something defined by >an existing common SAML profile, as far as I know.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri Light",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I believe AWS in fact wants me to go the unsupported way since it is exactly documented like the unsupported way
you describe. See: <a href="http://docs.aws.amazon.com/STS/latest/UsingSTS/CreatingSAML.html">
