X2GoClient: 4.0.3.1 on Windows 7 64-bit

I am using my domain account to remotely connect to my desktop (MATE or
Cinnamon), and I can do it successfully only if I try with a local user,
without backslashes.
Otherwise on Windows client I get "access denied from user", which is
supposed to be fixed on my x2go installed version (according to
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=704#45).

Clearly, from the logs at the bottom (server syslog), you can see that the
user connects correctly from the client, but then it parses incorrectly and
uses the wrong domain+name.
May 26 10:34:11 machineName /usr/bin/x2gostartagent: user
,,domain\username'' requests desktop sharing from user ,,domainusername''
for desktop ,,:0''
May 26 10:34:11 machineName /usr/bin/x2gostartagent: ERROR: user
domainusername denied desktop sharing session
May 26 10:34:11 machineName /usr/bin/x2gostartagent: ERROR: reason: for
desktop sharing denial the user ,,domainusername'' does not seem to have
desktop sharing activated

If I try to use domain\\username, which is a workaround on some SW, I get
the wrong username error.

Any more info needed?

Regards,

Diego
