In our system this is problematic=20 as access to $HOME requires a valid kerberos ticket, i.e. once the=20 ticket expires it can=E2=80=99t be renewed from within the X2Go session b= ecause=20 access to the ticket cache is denied. For normal logins, the krb5cc is=20 located at /tmp which prevents this problem. I=E2=80=99d appreciate an op= tion to=20 set the location where to put the ticket cache. I believe the current behaviour comes from src/onmainwindow.cpp:7332=20 where the location is more or less hard-coded. My suggestion would be to = add either a configuration option in the GUI or at least a command line=20 switch to change this location. I=E2=80=99m not familiar enough with the = code to=20 provide a patch but I think it should be not too difficult.
