Hi,
We've been facing a strange issue. Clients use X11 forwarding via SSH on HP server and sometimes the same DISPLAY is assigned to two (maybe more) sessions. As a result, some users can't open their applications, and some have their windows redirected to somebody else.
It looks as if sshd... (1 Reply)

pam_ck_connector
PAM_CK_CONNECTOR(8) ConsoleKit Manual PAM_CK_CONNECTOR(8)
NAME
pam_ck_connector - Register session with ConsoleKit
SYNOPSIS
pam_ck_connector.so [debug]
DESCRIPTION
The pam_ck_connector PAM module registers a login session with the system-wide ConsoleKit daemon. This PAM module should be used with
caution; only local login managers such as login(1) should use this. Since the ConsoleKit daemon can accept both an tty and an X11 display
the normal parameters set by PAM are not always useful.
An application can therefore override these with the PAM environment variables CKCON_TTY, CKCON_X11_DISPLAY and CKCON_X11_DISPLAY_DEVICE
(the application should remember to unset these before starting the login session).
Also note that the ConsoleKit daemon may reject registration attempts if the given set of data are inconsistent with each other. More more
information, see the ConsoleKit documentation on the OpenSessionWithParameters() method call on the org.freedesktop.ConsoleKit.Manager D-
Bus interface.
If registration with the ConsoleKit daemon succeeds, this PAM module will set the environment variable XDG_SESSION_COOKIE which is used to
defined membership of a login session.
This PAM module has the side effect that it creates a connection to the system message bus that is kept open until the session ends. This
is used by the ConsoleKit daemon to track the life-cycle of the session and, as such, should the login manager crash, the session will be
properly unregistered.
OPTIONS
debug
Print debug information.
nox11
Do not create a session if PAM specifies an X11 display instead of a /dev/tty terminal.
