[X2Go-Dev] Bug#1258: x2goclient hangs when connecting with Kerberos auth

[Mike DePaulo]

Package: x2goclient
Version: 4.1.1.0

When attempting to connect to an X2Go server with GSSAPI/Kerberos
auth, x2goclient hangs indefinitely.

This was observed with nightly builds for Windows, and was assumed to
be Windows-specific.

The fix has already been committed to master. I will update master
with another commit (& change to debian/changelog) stating that this
was fixed:
commit 7cbd8d525309edb8bd05d27ec57ac72e2d8c90e8
Author: Mike DePaulo 
Date:   Sun Feb 18 19:52:22 2018 -0500

Do not attempt to perform Interaction with SSH Server

(e.g. for changing expired password) when using GSSAPI/Kerberos
because the interaction code does not support it yet.


But as I was fixing it, I noticed that Linux & Mac OS X are probably
affected too.

The cause of the issue is that the new Interaction Dialog feature
introduced by this commit contains libssh-specific function calls, but
we use PuTTY binaries on Windows & the OpenSSH ssh client binary on
Linux/MacOS for GSSAPI/Kerberos:
commit 68bbf328132125eaad5c53b0ac82490bf818e42e
Author: Oleksandr Shneyder 
Date:   Wed May 10 15:22:11 2017 +0200

Interaction with SSH server (for example for changing expired
password). Fixes: #592.

And the "fix" for this is to bypass that new feature when
GSSAPI/Kerberos auth is used.

I will open up a separate issue about the fact that the Interaction
Dialog feature does not work with GSSAPI/Kerberos.

-Mike
