<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Amazon SP metadata originally contained the following:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><md:SPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol" WantAssertionsSigned="true"><o:p></o:p></p>
<p class="MsoNormal"> <md:AssertionConsumerService index="1" isDefault="true" Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://signin.aws.amazon.com/saml"><o:p></o:p></p>
<p class="MsoNormal"> <ServiceName xml:lang="en">AWS Management Console Single Sign-On</ServiceName><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="true" name="https://aws.amazon.com/SAML/Attributes/Role" FriendlyName="RoleEntitlement"/><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="true" name="https://aws.amazon.com/SAML/Attributes/RoleSessionName" FriendlyName="RoleSessionName"/><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="false" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.1" FriendlyName="eduPersonAffiliation"/><o:p></o:p></p>
<p class="MsoNormal"></md:AssertionConsumerService><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After successful authentication, I noticed this in the logs:<o:p></o:p></p>
<p class="MsoNormal"><b>20:20:51.810 - DEBUG [edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.ShibbolethAttributeResolver:275] - Specific attributes for principal XXX were not requested, resolving all attributes.<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As if the AttributeResolver did not recognize that the SP’s RequestedAttribute. I thought that this was caused by AWS not conforming to the SAML standard since I couldn’t find an example of including RequestedAttribute elements inside
AssertionConsumerService elements.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I thus modified the metadata to conform to the standard as I have understood it:<o:p></o:p></p>
<p class="MsoNormal"> <md:SPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol" WantAssertionsSigned="true"><o:p></o:p></p>
<p class="MsoNormal"> <md:AttributeConsumingService index="1"><o:p></o:p></p>
<p class="MsoNormal"> <ServiceName xml:lang="en">AWS Management Console Single Sign-On</ServiceName><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="true" name="https://aws.amazon.com/SAML/Attributes/Role" FriendlyName="RoleEntitlement"/><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="true" name="https://aws.amazon.com/SAML/Attributes/RoleSessionName" FriendlyName="RoleSessionName"/><o:p></o:p></p>
<p class="MsoNormal"> <RequestedAttribute isRequired="false" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.1" FriendlyName="eduPersonAffiliation"/><o:p></o:p></p>
<p class="MsoNormal"> </md:AttributeConsumingService><o:p></o:p></p>
<p class="MsoNormal">….<o:p></o:p></p>
<p class="MsoNormal">This didn’t work either; I received the exact same message. I therefore looked at the code and it appears it is looking for requested attributes in the AttributeAuthorityDescriptor element. What am I missing? I would like the IdP to
recognize the attributes requested by the SP, ideally in the AssertionConsumerService element so I don’t have to modify the provided metadata, or at the least AttributeConsumingService.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
