      Description

      When using Guacamole's RDP printer with resize-method property set to "reconnect", sometimes, when i resize navigator, the guacdr plugin doesn't map the same printer on reconnection.

      Connection configuration :

              <connection name="RDP-001">
                      <protocol>rdp</protocol>
                      <param name="hostname">****</param>
                      <param name="username">***</param> 
                      <param name="password">***</param>
                      <param name="enable-printing">true</param>
                      <param name="printer-name">PDF Printer</param> 
                      <param name="resize-method">reconnect</param>
                      <param name="port">3389</param>
              </connection>

      It seems that the packet PAKID_CORE_USER_LOGGEDON was never received by the guacdr plugin. (sometimes it's the packet PAKID_CORE_CLIENTID_CONFIRM).

       

      This issue appears randomly but never happens on the first connection (only when resizing display).
