* <u>Map HDA Apps Option 2 == Remote Desktop (RDP) Through OpenVPN ALS (Web Forwards Replacement ProxyAdito)<==Download the RDP extension from [http://lars.werner.no/u>adito-application-advancednativerdpwin32.zip here] and leave it as a .zip file to upload the extension.=== Credit Due ===** Login Nearly all of these instructions are taken from [http://lars.werner.no/?p=640 the work of Lars Werner]. His website has images as administratorwell and may be a better source of instruction. These notes are included here so that this hard-to-come-by information is not lost. If you go there, start on "Step 2." === Installing the RDP extension ===The Adito client can publish software to download and execute.Typical portable software is preferred, since clients does not always have registry write access. The RDP Extension uses the RDPsso.exe command from Microsoft and is based on the old less secure RDP. But you are connecting through a SSL encrypted tunnel, so it is considered “safe”. If you are not in managementconsole press the changebutton now (Third icon from the left located in the upper right of the Adito screen.

The default RDP port is 3389 and Descriptionis usally left alone.::(Note: You aren’t restricted to local-ips or -hosts here, you can also use internet hosts.Some people use the Adito server as the only entrypoint on their firewall)*Press next* Check <u>Step 4: Application Shortcut Policy Selection.</u> Click on "Everyone" in the left list and then click on the "Add " button. This gives permission to use the application to all users in the Everyone group.* Press next and look over the summary, then press Finish.  You have now published an app called whatever you called it in Step 2 to the group “Everyone”.That means that every user that you have, will gain access to this app.You can create as many applications as you need, just repeat the wizard === Java Security Considerations for RDP ===Before connecting to the RDP from a remote pc, you will need to add an exception to the remote pc's Java's URL Exception List to Favorites get passed the errors.
