What's New?

The enhancements and changes that are available in Build 51.19.

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.

Limitations

The list of limitations available in Build 51.19.

Citrix ADC SDX appliance

  • On the SDX 26xxx platform, a maximum of 26 CPU cores can be assigned to a VPX instance. However, if crypto units are assigned to the instance, the maximum number of cores depends on number of crypto units and data interfaces. For example, if you assigns 24000 crypto units to an instance, you can assign 24 CPU cores and maximum two data interfaces to the instance. The SDX appliance considers data interfaces and crypto units as PCI devices. With 26000 crypto units, a VPX instance cannot be provisioned since there is no room for data interfaces.

What's New in Previous Citrix ADC 12.1 Releases

The enhancements and changes that were available in Citrix ADC 12.1 releases prior to Build 51.19. The build number provided below the issue description indicates the build in which this enhancement or change was provided.

Authentication, authorization, and auditing

  • Support for validating end-to-end RADIUS authentication
    Citrix ADC appliance can now validate end-to-end RADIUS authentication through Citrix ADC GUI. A new “test” button is introduced in Citrix ADC GUI to validate this feature. A Citrix ADC administrator can use this feature to achieve the following benefits:
    - Consolidates the complete flow (packet engine – AAA daemon – external server) to provide better analysis.
    - Reduces time on validating and troubleshooting issues related to individual scenarios.

Fixed Issues in Previous Citrix ADC 12.1 Releases

The issues that were addressed in Citrix ADC 12.1 releases prior to Build 51.19. The build number provided below the issue description indicates the build in which this issue was addressed.

AAA-General

  • Feature: Authentication, authorization, and auditing
    Support for push notification OTP
    Citrix Gateway now supports push notification OTP. You can configure Citrix Gateway such that login notifications are sent to your registered devices using push notification services. When you receive the notification OTP, you have to simply tap Allow on the notification to log in to Citrix Gateway. Once Citrix Gateway receives the OTP, it verifies the OTP, identifies source of the request, and sends response to that browser connection.
