# pam\_ck\_connector(8)

Register session with ConsoleKit

## 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)](/login/1.md)** 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.
