+pam_keyinit — Kernel session keyring initialiser module
+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:
+ Log debug information with syslog(3).
+ Causes the session keyring of the invoking process to be replaced
+ unconditionally.
+ 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.
+Add this line to your login entries to start each login session with its own
+session keyring:
+session required
+This will prevent keys from one session leaking into another session for the
+same user.
