Mihai, please correct me if I'm wrong, but I think the situation is more
like this: The earlier libssh version we used didn't support agent
forwarding, the newer one does, but it doesn't work with X2GoClient yet,
at least not in all cases.  That's why you're suddenly seeing an
SSH_AUTH_SOCK variable set, but e.g. pointing to a non-existent file.

So yes, there's still work to do, but the new libssh should make it at
least easier.

Sponsors, anyone? ;-)

Kind Regards,
Stefan Baur
