The Remember Me feature allows users to log on automatically with a specified user name and password to access their iRAPP connection.  You can enable this feature by accessing the Workspace options before a connection is established, on the Client machine.  Open the client connection menu and click the "Options" button. 

Then, on the "General" tab, select the option for "Logon Automatically" and enter the specified user name and password.

Click "OK" to save the settings.

Please Note:  This feature is supported by iRAPP Server for Mac OS 10.5 (Leopard) only.  Also, this feature is available on iRAPP client and iRAPP protocol only; not available with RDP.
