Shibboleth IDP (V4.2.1) and Neod/Neogov setup

[Nadim El-Khoury]

Hi Everyone,

We are trying to set up Single Sign-On between us and Neod/Neogov and it is
not working.

We dynamically consume their Metadata through InCommon, and they require
that the SAML NameID be persistent and in the email address format.

Their metadata is below.

<md:EntityDescriptor entityID="https://login.neoed.com/"
ID="_697e849a-7a17-43e7-8034-fcae23e2767d">
<md:SPSSODescriptor ID="_8153bed2-27cb-4e3a-b2f1-664a2325f71e"
protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">
<md:NameIDFormat>
urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
</md:NameIDFormat>
<md:NameIDFormat>
urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
</md:NameIDFormat>
<md:AssertionConsumerService
Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="
https://login.neoed.com/authentication/saml/consumer" index="0"
isDefault="true"/>
<md:AttributeConsumingService index="1" isDefault="true">
<md:ServiceName xml:lang="en">Neogov SSO</md:ServiceName>
<md:RequestedAttribute isRequired="true"
Name="urn:oid:0.9.2342.19200300.100.1.3"
NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"
FriendlyName="mail"/>
</md:AttributeConsumingService>
</md:SPSSODescriptor>
</md:EntityDescriptor>

We see the following message in the SAML tracer file and the logs.

2022-11-14 15:15:48,830 - 10.2.50.21 - WARN
[org.opensaml.saml.saml2.profile.impl.AddNameIDToSubjects:334] - Profile
Action AddNameIDToSubjects: Request specified use of an unsupportable
identifier format: urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

2022-11-14 15:15:48,834 - 10.2.50.21 - WARN
[org.opensaml.profile.action.impl.LogEvent:101] - A non-proceed event
occurred while processing the request: InvalidNameIDPolicy

We did not know whether we needed to uncomment the following line in
saml-nameid.xml or create a SAML2AttributeSourceGnerator that I am
including below.

        <!--

        <ref bean="shibboleth.SAML2PersistentGenerator" />

        -->


<bean parent="shibboleth.SAML2AttributeSourcedGenerator"

                p:omitQualifiers="true"


p:format="urn:oasis:names:tc:SAML:1.1:nameid-format:persistent"

                p:attributeSourceIds="#{ {'mail'} }"

                p:activationCondition-ref="PersistentMailCondition" >

        </bean>

Your help or direction is very much appreciated.

Best,

Nadim
