  • In conf/idp.properties, uncomment and set 'idp.encryption.optional' to true.
       eg. idp.encryption.optional = true
  • In conf/metadata-providers.xml, configure Service Provider like this
    • <MetadataProvider xmlns:samlmd="urn:oasis:names:tc:SAML:2.0:metadata"
      id="miniOrangeInLineEntity" xsi:type="InlineMetadataProvider" sortKey="1">
      <samlmd:EntityDescriptor ID="entity" entityID="<SP-EntityID / Issuer from Service Provider Info tab in plugin.>"
        validUntil="2020-09-06T04:13:32Z">
        <samlmd:SPSSODescriptor AuthnRequestsSigned="false" WantAssertionsSigned="true"
        protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">
          <samlmd:NameIDFormat>
            urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
          </samlmd:NameIDFormat>
        <samlmd:AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"
        Location="<ACS (AssertionConsumerService) URL from Step1 of the plugin under Identity Provider Tab.>"
          index="1" />
        </samlmd:SPSSODescriptor>
        </samlmd:EntityDescriptor>
    </MetadataProvider>
  • In conf/saml-nameid.properties, uncomment and set default NameID as Email Address like this
    • idp.nameid.saml2.default=urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
  • In conf/saml-nameid-xml, search for shibboleth.SAML2NameIDGenerators. Uncomment the shibboleth.SAML2AttributeSourcedGenerator bean and comment all other ref beans
    • <!-- SAML 2 NameID Generation -->
    <util:list id="shibboleth.SAML2NameIDGenerators">
      <!--<ref bean="shibboleth.SAML2TransientGenerator" /> -->
      <!-->ref bean="shibboleth.SAML2PersistentGenerator" /> -->
      <bean parent="shibboleth.SAML2AttributeSourcedGenerator"
      p:format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
      p:attributeSourceIds="#{ {'email'} }" />
    </util:list>
  • Make sure you have defined AttributeDefinition in conf/attribute-resolver.xml.
    • <!-- Note: AttributeDefinitionid must be same as what you provided in attributeSourceIds in conf/saml-nameid.xml -->
    <resolver:AttributeDefinitionxsi:type="ad:Simple" id="email" sourceAttributeID="mail">
      <resolver:Dependency ref="ldapConnector" />
      <resolver:AttributeEncoderxsi:type="enc:SAML2String" name="email" friendlyName="email" />
    </resolver:AttributeDefinition >

    <resolver:DataConnector id="ldapConnector" xsi:type="dc:LDAPDirectory" ldapURL="%{idp.authn.LDAP.ldapURL}"
      baseDN="%{idp.authn.LDAP.baseDN}" principal="%{idp.authn.LDAP.bindDN}"
      principalCredential="%{idp.authn.LDAP.bindDNCredential}">
      <dc:FilterTemplate>
        <!-- Define you User Search Filter here -->
        <![CDATA[ (&(objectclass=*)(cn=$requestContext.principalName)) ]]>
      </dc:FilterTemplate>

      <dc:ReturnAttributes>*</dc:ReturnAttributes>
    </resolver:DataConnector>
  • Make sure you have AttributeFilterPolicy defined in conf/attribute-filter.xml.
    • <afp:AttributeFilterPolicy id="ldapAttributes">
    <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
    Single Logout URL https://<your_domain>/idp/shibboleth
    X.509 Certificate The public key certificate of your Shibboleth server

Step 2: Configuring Drupal as Service Provider (SP)

      • Drupal shibboleth sso icon-1 By Shibboleth3 Metadata URL :

      • Click on Upload IDP Metadata.
      • Enter Metadata URL and click on Fetch Metadata.

      Drupal shibboleth sso icon-2 By Uploading Shibboleth3 Metadata File:

      • Click on Upload IDP Metadata.
      • Upload metadata file and click on Upload.

      Drupal shibboleth sso icon-3 Manual Configuration :

      • Copy SAML Entity ID, SAML Single-Sign-On Endpoint URL and X.509 certificate from Federation Metadata document and paste it in IdP Entity ID or Issuer, SAML Login URL, X.509 Certificate fields respectively in the Module.
      Identity Provider Name For Example:Shibboleth3
      IdP Entity ID or Issuer SAML Entity ID in the Federation Metadata document
      SAML Login URL SAML Single-Sign-On Endpoint URL in the Federation Metadata document
      X.509 Certificate x.509 Certificate in the Federation Metadata document

Step 3: Attribute Mapping (It is Optional to fill this.) This is Premium feature.

  • Attributes are user details that are stored in your Identity Provider.
  • Attribute Mapping helps you to get user attributes from your Identity Provider (IdP) and map them to Drupal user attributes like firstname, lastname etc.
  • While auto registering the users in your Drupal site these attributes will automatically get mapped to your Drupal user details.
  • In miniOrange SAML Module, go to Mapping tab and fill in all the fields.
    Username: Name of the username attribute from IdP (Keep NameID by default)
    Email: Name of the email attribute from IdP (Keep NameID by default)
    Group/Role Key: Name of the Role attribute from Identity Provider (IdP)
    • Drupal shibboleth sso attribute mapping
  • You can check the Test Configuration Results under Service Provider Setup tab to get a better idea of which values to map here.

Step 4: Role mapping. (It is Optional to fill this.) This is Premium feature.

  • Drupal uses a concept of Roles, designed to give the site owner the ability to control what users can and cannot do within the site.
  • Role mapping helps you to assign specific roles to users of a certain group in your Identity Provider (IdP).
  • While auto registering, the users are assigned roles based on the group they are mapped to.
    • Drupal shibboleth sso role mapping
