pam_keyinit -- Kernel session keyring initialiser module
     __________________________________________________________________

DESCRIPTION

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

   The module checks to see if the process's session keyring is the
   user-session-keyring(7), and, if it is, creates a new
   session-keyring(7) with which to replace it. If a new session keyring
   is created, it will install a link to the user-keyring(7) 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.

   In order to allow other PAM modules to attach tokens to the keyring,
   this module provides both an auth (limited to pam_setcred(3) and a
   session component. The session keyring is created in the module called.
   Moreover this module should be included as early as possible in a PAM
   configuration.

   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.

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

   Keyutils

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.

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.
