There is some limitation in PAM built-in RDP client so RDP Proxy service has been configured as below.
Using this RDP Proxy Service, PAM will invoke a local Microsoft RDP client (mstsc), instead of PAM built-in RDP client, to connect to a target Windows server. However, how can we configure drive mapping in this configuration?
To enable mapping drive when you are using RDP Proxy, please select "RDP Drive Mapping" in Configuration > RDP Proxy > RDP Proxy Configuration tab.
You can also configure "Copy and Paste" feature in the same above configuration page.
For more information about configuring an RDP proxy service, please refer to the documentation link below: Configure RDP Proxy Service Settings.
