Subject: x2goserver and rhel6.4 / selinux Problem

Package: x2goserver
Version: 4.0.1.13


Hello,

on a scientific linux 6.4 system with selinux enabled (RedHat Clone) I 
have the following problem with x2goserver-4.0.1.13-2.el6.x86_64:

After connecting with x2goclient to the server system, the .Xauthority 
file my home directory is created with the following selinx
permissions:

---------------------------

ls -Z .Xauthority

-rw-------. frank users unconfined_u:object_r:default_t:s0 .Xauthority

--------------------------

Then I do a logout. Now, when I try to connect again to the x2go server 
system, I get
the following error message on the client side and no session is started.

-----------------------------
.....

"Warning: Cookie mismatch in the X authentication data.
"

"Session: Terminating session at 'Thu Feb 27 09:40:05 2014'.
Info: Your session was closed before reaching a usable state.
Info: This can be due to the local X server refusing access to the client.
Info: Please check authorization provided by the remote X application.
Session: Session terminated at 'Thu Feb 27 09:40:05 2014'.
"

deleting proxy

nxproxy not running

proxy deleted

-----------------------------------

But when I change the selinux permissions to

------

ls -Z .Xauthority

-rw-------. frank users unconfined_u:object_r:xauth_home_t:s0 .Xauthority

-----

with the command

/usr/bin/chcon unconfined_u:object_r:xauth_home_t:s0 .Xauthority*

there is no problem logging in to the x2goserver system the next time.

Can this be fixed in the x2goserver software?

Sincerly
