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

        • includeAttributeStatement: Yes
        • assertionLifeTime: 300000
        • signResponse: conditional
        • signAssertions: never
        • signRequests: conditional
        • encryptAssertions: never
        • encryptNameIds: never
    • Released attributes:
      • lastnamewebex
      • uidwebex
