Cisco WebEx configuration in Gluu Server v3

Custom Attribute Creation

We need to create couple of custom attributes and one custom nameID. List of custom attributes and nameID is stated below. Here is how we can create custom attributes.

• uidwebex
• emailwebex
• firstnamewebex
• lastnamewebex
• webexnameid

In secord part ( oxTrust operation ) of creating custom attribute, we need to follow couple of points for these special attributes. Here is how each attribute should be created:

• uidwebex:

  • Name: uidwebex
  • SAML1 URI: uid
  • SAML2 URI: uid
  • DisplayName: uidwebex
  • Type: Text
  • Rest are default values.

• emailwebex:

  • Name: emailwebex
  • SAML1 URI: email
  • SAML2 URI: email
  • DisplayName: wxemail
  • Rest are default values

• wxfirstname

  • Name: firstnamewebex
  • SAML1 URI: firstname
  • SAML2 URI: firstname
  • DisplayName: wxfirstname
  • Type: Text
  • Rest are default values.

• wxlastname:

  • Name: lastnamewebex
  • SAML1 URI: lastname
  • SAML2 URI: lastname
  • DisplayName: wxlastname
  • Rest are default values.

• webexnameid

  • Name: webexnameid
  • SAML1 URI: urn:gluu:dir:attribute-def:webexnameid
  • SAML2 URI: urn:oid:webexnameid
  • DisplayName: webexnameid
  • Type: Text
  • Rest are default values.

WebEx Attribute generation

We need to modify attributeDefinition for these attributes. Configuration is applied in attribute-resolver.xml.vm file which is located in /opt/gluu/jetty/identity/conf/shibboleth3/idp/

Attribute Definition

• Attribute 'uidwebex':
  • Add 'uidwebex' in 'if statement':

    #if( ! ($attribute.name.equals('transientId') or $attribute.name.equals('persistentId') $attribute.name.equals('uidwebex') ) )
    

  • Declaration of 'uidwebex':

<resolver:AttributeDefinition xsi:type="ad:Simple" id="uidwebex" sourceAttributeID="uidwebex">
        <resolver:Dependency ref="siteLDAP" />
        <resolver:AttributeEncoder xsi:type="enc:SAML2String" nameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified" name="uid" />
</resolver:AttributeDefinition>

- Attribute 'emailwebex': - Append 'emailwebex' in 'if statement':

#if( ! ($attribute.name.equals('transientId') or $attribute.name.equals('persistentId') or $attribute.name.equals('uidwebex') or $attribute.name.equals('emailwebex') ) )

- Declaration of 'emailwebex':

<resolver:AttributeDefinition xsi:type="ad:Simple" id="emailwebex" sourceAttributeID="emailwebex">
        <resolver:Dependency ref="siteLDAP" />
        <resolver:AttributeEncoder xsi:type="enc:SAML2String" nameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified" name="email" />
    </resolver:AttributeDefinition>

- Attribute 'firstnamewebex': - Append 'firstnamewebex' in 'if statement' just like above attributes - Declaration of 'firstnamewebex':

<resolver:AttributeDefinition xsi:type="ad:Simple" id="firstnamewebex" sourceAttributeID="firstnamewebex">
        <resolver:Dependency ref="siteLDAP" />
        <resolver:AttributeEncoder xsi:type="enc:SAML2String" nameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified" name="firstname" />
    </resolver:AttributeDefinition>

- Attribute 'lastnamewebex': - Append 'lastnamewebex' in 'if statement' - Declaration of 'lastnamewebex':

<resolver:AttributeDefinition xsi:type="ad:Simple" id="lastnamewebex" sourceAttributeID="lastnamewebex">
        <resolver:Dependency ref="siteLDAP" />
        <resolver:AttributeEncoder xsi:type="enc:SAML2String" nameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified" name="lastname" />
</resolver:AttributeDefinition>

• NameID 'webexnameid':
  • Append 'webexnameid' in 'if statement'
  • Declaration of 'webexnameid':

<resolver:AttributeDefinition id="webexnameid"
        xsi:type="Simple"
        xmlns="urn:mace:shibboleth:2.0:resolver:ad"
        sourceAttributeID="mail">
    <resolver:Dependency ref="siteLDAP" />
    <resolver:AttributeEncoder xsi:type="SAML2StringNameID"
             xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
             nameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"/>
 </resolver:AttributeDefinition>

• SAML2 NameID Generation:
  • File: saml-nameid.xml
  • Location: /opt/shibboleth-idp/conf
  • Add bean inside SAML2 NameID util:list

<bean parent="shibboleth.SAML2AttributeSourcedGenerator"
    p:format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
    p:attributeSourceIds="#{ {'webexnameid'} }" />

• Restart 'idp' and 'identity' services with:
  • service idp restart
  • service identity restart

Trust Relationship

• Grab WebEx metadata and remove all Name Identifier other than emailAddress. Save this newly modified metadata
• Log into oxTrust
• SAML > Add Trust Relationships
  • DisplayName: WebEx
  • Description: anything is fine
  • Entity Type: Single SP
  • Metadata Location: File
  • SP Metadata File: upload newly modified metadata
  • Upload public certificate: not required
  • SP Logout URL: not required
  • Configure Relying Party: Yes
    • SAML2SSO:
      • includeAttributeStatement: Yes
      • assertionLifeTime: 300000
      • signResponse: conditional
      • signAssertions: never
      • signRequests: conditional
      • encryptAssertions: never
      • encryptNameIds: never
  • Released attributes:
    • lastnamewebex
    • uidwebex
    • webexnameid
    • wxemail
    • wxfistname
