pam_ck_connector - Register session with ConsoleKit

pam_ck_connector.so [debug]

The pam_ck_connector PAM module registers a login session with the system-wide ConsoleKitdaemon. This PAM module should be used with caution; only local login managers such as

login(1) should use this. Since the ConsoleKitdaemon 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 ConsoleKitdaemon may reject registration attempts if the given set of data are inconsistent with each other. More more information, see the ConsoleKitdocumentation on the

OpenSessionWithParameters() method call on the

org.freedesktop.ConsoleKit.Manager D-Bus interface. If registration with the ConsoleKitdaemon 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 ConsoleKitdaemon to track the life-cycle of the session and, as such, should the login manager crash, the session will be properly unregistered.

     Print debug information.
• nox11    Do not create a session if PAM specifies an X11 display instead of a /dev/tty terminal.
