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.
