<p class="MsoNormal">Hi Everyone-<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We occasionally receive assertions which contain multi ePPN attributes. Usually, they are the same value, but our apps receive them as multi-valued (e.g.
<a href="mailto:value@domain.edu;value@domain.edu">value@domain.edu;value@domain.edu</a>).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I know this is an IdP configuration problem, but we have apps that assume ePPN to be single-valued (as the spec for that says), so we’d like to limit the SP to presenting only one value to the apps.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We’ve tried to use a PermitValueRule for this and we’ve tried a few different things, but we always seem to end up with no ePPN values seen by the apps.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here’s the one we’ve tried that seems like it should work since it follows other similar examples in the attribute-policy.xml file:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> <PermitValueRule id="SingleValue"><o:p></o:p></p>
<p class="MsoNormal"> <Rule xsi:type="NumberOfAttributeValues" minimum="1" maximum="1"/><o:p></o:p></p>
<p class="MsoNormal"> </PermitValueRule><o:p></o:p></p>
<p class="MsoNormal">….<o:p></o:p></p>
<p class="MsoNormal"> <AttributeRule attributeID="eppn"><o:p></o:p></p>
<p class="MsoNormal"> <PermitValueRule xsi:type="AND"><o:p></o:p></p>
<p class="MsoNormal"> <RuleReference ref="ScopingRules"/><o:p></o:p></p>
<p class="MsoNormal"> <RuleReference ref="SingleValue"/><o:p></o:p></p>
<p class="MsoNormal"> </PermitValueRule><o:p></o:p></p>
<p class="MsoNormal"> </AttributeRule><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone point us in the right direction?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">TIA,<o:p></o:p></p>
