What is SSO ?

Single sign-on (SSO) is an authentication method that enables users to access multiple applications with  one-click login  and one set of credentials. For example, after users log in to your org, they can automatically access all apps from the App Launcher. When you set up SSO, you configure one system to trust another to authenticate users , eliminating users' need to log in to each system separately. The system that authenticates users is called an Identity provider. The system that trusts the identity provider for authentication is called the Service provider.

SAML allows exchanging of information between Service Provider and Identity provider, SAML is integration between SP and IDP. When a user tries to log in, your identity provider sends SAML assertions containing facts about the user to Identity Provider. Identity Provider receives the assertion, validates it against your Identity Provider configuration, and allows the user to access your org.

Here we will go through a guide to configure SAML SSO between Joomla and your Identity Provider. By the end of this guide, users from your Identity Provider should be able to login and register to Joomla site.

Step 1: Setup Shibboleth3 as Identity Provider

  • 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
