Shibboleth2 as IdP – SAML

Step 1: Set Up Shibboleth2 as Identity Provider

  • In conf/relying-party.xml, configure Service Provider like this
    • <MetadataProviderxsi:type="InlineMetadataProvider" xmlns="urn:mace:shibboleth:2.0:metadata" id="MyInlineMetadata">
      <EntitiesDescriptorxmlns="urn:oasis:names:tc:SAML:2.0:metadata">
        <md:EntityDescriptorxmlns:md="urn:oasis:names:tc:SAML:2.0:metadata" entityID="<ENTITY_ID_FROM_PLUGIN>">
          <md:SPSSODescriptorAuthnRequestsSigned="false" WantAssertionsSigned="true" protocolSupportEnumeration=
              "urn:oasis:names:tc:SAML:2.0:protocol">
            <urn:oasis:names:tc:SAML:1.1:nameidformat:emailAddress</md:NameIDFormat>
            <md:AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:https-POST"
              Location="<ACS_URL_FROM_PLUGIN>" index="1"/>
          </md:SPSSODescriptor>
        </md:EntityDescriptor>
      </EntitiesDescriptor>
    </MetadataProvider>


  • Make sure your Shibboleth server is sending Email Address of the user in Name ID. In attribute-resolver.xml, get the email attribute as Name ID:
    • <resolver:AttributeDefinitionxsi:type="ad:Simple" id="email" sourceAttributeID="mail">
       <resolver:Dependency ref="ldapConnector" />
       <resolver:AttributeEncoderxsi:type="enc:SAML2StringNameID" nameFormat="urn:oasis:names:tc:SAML:1.1:
        nameid-format:emailAddress"/>
    </resolver:AttributeDefinition>

  • In attribute-filter.xml, release the email attribute:
    • <afp:AttributeFilterPolicy id="releaseTransientIdToAnyone">
    <afp:PolicyRequirementRulexsi:type="basic:ANY"/>
      <afp:AttributeRuleattributeID="email">
        <afp:PermitValueRulexsi:type="basic:ANY"/>
      </afp:AttributeRule>
    </afp:AttributeFilterPolicy>

  • Restart the Shibboleth server.
  • You need to configure these endpoints in miniOrange plugin.
    • IDP Entity ID https://<your_domain>/idp/shibboleth
    Single Login URL https://<your_domain>/idp/profile/SAML2/Redirect/SSO
    X.509 Certificate The public key certificate of your Shibboleth server
