[X2go-dev] Errors in DOMAIN\Username behaviour / followup to LDAP problems

Hey guys,

first of all - thanks a lot for making this software possible, it's
definitely the best NX/Linux-Terminal connection software out there atm
so please keep up the good work!

My report is a followup to messages from mid december concerning LDAP
user problems (e.g. with pulseaudio). I am using winbind authentication
on an x2goserver so I have to deal with special characters in usernames
as well like DOMAIN\username or username at DOMAIN. There's no workaround
for that since I'm in a multi-trusted domain environment, no default
possible.

When I login as a local user e.g. sysop everything works fine (Ubuntu
10.04 x64, latest x2goserver from heuler repo: 3.0.99 and latest client
3.01-17 under Tinycore Linux, log attached). When I login as an winbind
user USER\huhs01868030 miscellaneous files and directories are not
created. I'm attaching a $ find .x2go for all cases.

Among them are:
.pulse-client.conf
.pulse-cookie
cmdoutput
keys under ssh/
link to spool directory

It seems that there are problems when functions like ssh_scp_push_file()
from libssh are called. Log shows they are called with double quotes for
parameters (although IMHO it should be better to call them with single
quotes - the difference lies in handling escape sequences as they are
interpreted with double quotes and left out with single quotes, but
that's a guess from me ;).

I'm also attaching changes for sshmasterconnection.cpp which solved the
problems to a certain degree by escaping the back slashes again before
throwing them over to libssh. However spool directory and cmdoutput are
still not created but that seems to be server related too.

Another code fragment I don't understand and which causes errors in my
case is the definition of dst in onmainwindow_part3.cpp on line 899.

dst="~"+uname +"/.x2go/ssh"+dst;

According to the log this results in x2goclient trying to create keys in
"~USER\huhs01868030/.x2go/ssh", which is surely not working. Attached
patch works for me with just letting uname out of dst.

I can provide more details and tests if you like to see them.

Best regards and greetings from Berlin,

Robert
