It is possible to use Windows 2012 with NLA support enabled. NLA is supported by VISULOX PORTAL with ttatsc.
If a Windows 2012 / NLA session is connected to Filetransfer, vlxShell -client freerdp -drive X has to be used.
If freeRDP is used without NLA, the --no-nla parameter must be set.
vlxShell with freeRDP is working with vlxSSO=1 to provide primary login credentials to Windows. If needed, also with extra vlxUser and vlxPWD.
If a drive is assigned with -drive <letter>, the according Windows or Citrix server must provide this drive.
