Administrators attempting to configure Citrix Conditional Authentication find that the option to utilize custom URLs or domains is unavailable. There is no apparent setting within the Conditional Authentication configuration interface to input or apply a custom URL.
Unfortunately, there is no immediate workaround to enable the use of custom URLs with Citrix Conditional Authentication at this time. The functionality is simply not yet implemented.
The Citrix documentation indicates that support for custom domains is a roadmap item for future updates. This means that the ability to use custom URLs with Conditional Authentication is planned for a future release of Citrix Cloud.
As explicitly stated in the official Citrix product documentation for Conditional Authentication, custom domains are not currently supported. This limitation is by design in the current iteration of the feature. The documentation clearly lists this as a known issue and limitation.
