Additional Changes/Fixes Available in Versions

What's New?

The enhancements and changes that are available in Build 51.16.

Authentication, authorization, and auditing

  • Custom attributes support on OpenID Connect
    A Citrix ADC appliance configured as an IdP can now send extra attributes in the OpenID Connect id_token using expressions. Advanced policy expressions are used to send the custom attributes as per the requirement. The Citrix IdP evaluates the expressions corresponding to the attributes and then computes the final token with resulting values.
    For more information, see https://docs.citrix.com/en-us/citrix-adc/12-1/aaa-tm/configuring-openid-connect-protocol.html#custom-attributes-support-on-openid-connect

Known Issues

The issues that exist in Build 51.16.

Authentication, Authorization, and Auditing

  • The back end is not accessible through a clientless VPN (CVPN). The issue occurs when SSO is ON, the proxy is specified in a traffic action, and the back-end credentials are different from the logon credentials.
    Workaround:
    Create a traffic policy based on back-end URL and create a trafficAction with SSO OFF and No Proxy. The backend should be accessible.
