Drupal Shibboleth SSO | SAML SSO Into Drupal Using Shibboleth 2

Step 1: Configuring Shibboleth2 as Identity Provider ( IDP )

• In conf/relying-party.xml, configure Service Provider like this
<MetadataProviderxsi:type="InlineMetadataProvider" xmlns="urn:mace:shibboleth:2.0:metadata" i d="MyInlineMetadata">
  <EntitiesDescriptorxmlns="urn:oasis:names:tc:SAML:2.0:metadata">
    <md:EntityDescriptorxmlns:md="urn:oasis:names:tc:SAML:2.0:metadata" e ntityID="<ENTITY_ID_FROM_PLUGIN>">
      <md:SPSSODescriptorAuthnRequestsSigned="false" WantAssert ionsSigned="true" protocolSupportEnumeration=
          "urn:oasis:names:tc:SAML:2.0:protoco l">
        <urn:oasis:names:tc:SAM L:1.1:nameidformat:emailAddress</md:NameIDFormat>
        <md:AssertionConsumerService Binding="urn:oas is: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 the Service Provider.

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
