Hello.

I can not solve problem with X apps. running as another user, using SSH
and IPv6. Connection with -X6 key passes OK and a i get access to the
users command line, but it still does not let me run X app. because ssh
client tries to set some X session environment using IPv4 protocol, and
gets denied.

What should be configured more in order to use IPv6 with the X session
access through SSH? Or there is a better (faster, easier yet safe) way
how one user can run X-apps under another user?
