Kerberos Constrained Delegation at Remote Desktop Session Host

we have the following configuration in our F5: After entering the login data (user name + token) on the logon page, you will be authenticated to a radius server. Then you can open a Remote Desktop Session Host to our terminal server pool. Here we would like to use Kerberos Constrained Delegetion to prevent re-authentication. Does anyone have experience with kerberos and remote desktop sessions, how should this be configured?
