 ### Requirements for remote desktop gateway machines
 - SSL certificate must be installed  on the gateway machine to handle HTTPS traffic. The certificate must match the fully qualified domain name (FQDN) of the load balancer for the gateway farm or the FQDN of the machine itself if there's only one machine. Wild-card SSL certificates don't work.  
 - A signing certificate installed on gateway machine(s). Create a signing certificate by using [Create-SigningCertificate.ps1](https://github.com/Azure/azure-devtestlab/blob/master/samples/DevTestLabs/GatewaySample/tools/Create-SigningCertificate.ps1) script.
-- Install the [Pluggable Authentication](https://code.msdn.microsoft.com/windowsdesktop/Remote-Desktop-Gateway-517d6273) module that supports token authentication for the remote desktop gateway. One example of such a module is `RDGatewayFedAuth.msi` that comes with [System Center Virtual Machine Manager (VMM) images](/system-center/vmm/install-console?view=sc-vmm-1807). For more information about System Center, see [System Center documentation](https://docs.microsoft.com/system-center/).

 - The gateway server can handle requests made to `https://{gateway-hostname}/api/host/{lab-machine-name}/port/{port-number}`.
 
     The gateway-hostname is the FQDN of the load balancer of the gateway farm or the FQDN of machine itself if there's only one machine. The `{lab-machine-name}` is the name of the lab machine that you're trying to connect, and the `{port-number}` is port on which the connection will be made.  By default, this port is 3389.  However, if the virtual machine is using the [shared IP](devtest-lab-shared-ip.md) feature in DevTest Labs, the port will be different.
