Using openAm as an IDP and another service provider throws Exception with Name ID Format

Question

I am trying to configure SSO for my application using OpenAm as IDP and application itself as service provider.

Folowing is the metadata of the IDP and Service Provider:

  <EntityDescriptor entityID="http://www.cpfdomain.com:8091/openam_10.0.1" xmlns="urn:oasis:names:tc:SAML:2.0:metadata">

</IDPSSODescriptor>

Service Provider Metadata:

<EntityDescriptor xmlns="urn:oasis:names:tc:SAML:2.0:metadata" entityID="test">
    <SPSSODescriptor AuthnRequestsSigned="false" WantAssertionsSigned="true" protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">

                    <X509Certificate>Key Info</X509Certificate>
                </X509Data>
            </KeyInfo>
        </KeyDescriptor>
        <SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" Location="LOGOUT LOCATION URI" ResponseLocation="LOGOUT LOCATION URI"/>
        <NameIDFormat>urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
        </NameIDFormat>
        <AssertionConsumerService index="0" isDefault="true" Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="ASSERTION URI"/>
    </SPSSODescriptor>
</EntityDescriptor>

When I test the federation, I always get the following error:

message Error processing AuthnRequest. Service provider does not support name identifier format urn:oasis:names:tc:SAML:2.0:nameid-format:transient.

I have removed this identifier from both IDP and SP in the circle of trust I am testing.

Any help would be appreciated.

Thanks.

As you have removed NameIdFormat 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient' from both IdP and SP MetaData you can not use it ... this should be obvious.

Of course you have to test SSO by specifying a NameIdFormat which both entities support ... in your case 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress'.

To test IdP-initiated SSO with HTTP-POST Binding use ...

OPENAM_SCHEME://OPENAM_FQDN:OPENAM_PORT/OPENAM_DEPLOYMENT_URI/idpssoinit?NameIDFormat=urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress&metaAlias=IDP_META_ALIAS&spEntityID=test&binding=urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST

Using openAm as an IDP and another service provider throws Exception with Name ID Format
