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.

NAME

       pam_keyinit - Kernel session keyring initialiser module

SYNOPSIS

       pam_keyinit.so [debug] [force] [revoke]

DESCRIPTION

       The pam_keyinit PAM module ensures that the invoking process has a session keyring other than the user default session keyring.

       The session component of the module checks to see if the process's session keyring is the user default, and, if it is, creates a new
       anonymous session keyring with which to replace it.

       If a new session keyring is created, it will install a link to the user common keyring in the session keyring so that keys common to the
       user will be automatically accessible through it.

       The session keyring of the invoking process will thenceforth be inherited by all its children unless they override it.

       This module is intended primarily for use by login processes. Be aware that after the session keyring has been replaced, the old session
       keyring and the keys it contains will no longer be accessible.

       This module should not, generally, be invoked by programs like su, since it is usually desirable for the key set to percolate through to
       the alternate context. The keys have their own permissions system to manage this.

       This module should be included as early as possible in a PAM configuration, so that other PAM modules can attach tokens to the keyring.

       The keyutils package is used to manipulate keys more directly. This can be obtained from:

       Keyutils[1]

OPTIONS

       debug
	   Log debug information with syslog(3).

       force
	   Causes the session keyring of the invoking process to be replaced unconditionally.

       revoke
	   Causes the session keyring of the invoking process to be revoked when the invoking process exits if the session keyring was created for
	   this process in the first place.

MODULE TYPES PROVIDED

       Only the session module type is provided.

RETURN VALUES

       PAM_SUCCESS
	   This module will usually return this value

       PAM_AUTH_ERR
	   Authentication failure.

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_IGNORE
	   The return value should be ignored by PAM dispatch.

       PAM_SERVICE_ERR
	   Cannot determine the user name.

       PAM_SESSION_ERR
	   This module will return this value if its arguments are invalid or if a system error such as ENOMEM occurs.

       PAM_USER_UNKNOWN
	   User not known.

EXAMPLES

       Add this line to your login entries to start each login session with its own session keyring:

	   session  required  pam_keyinit.so

       This will prevent keys from one session leaking into another session for the same user.
