This directory contains the modules.
If you want to reserve a module name please email <pam-list@redhat.com>
and announce its name. Andrew Morgan, <morgan@linux.kernel.org>, will
add it to the Makefile in the next release of Linux-PAM.
As of Linux-PAM-0.40 modules can optionally conform to the static
modules conventions.
This file was updated for Linux-PAM-0.53.
The conventions are as follows:
There are only 6 functions that a module may declare as "public" they
fall into 4 managment groups as follows:
functions Management group
------------------------------------------ ----------------
pam_sm_authenticate, pam_sm_setcred, PAM_SM_AUTH
pam_sm_acct_mgmt, PAM_SM_ACCOUNT
pam_sm_open_session, pam_sm_close_session, PAM_SM_SESSION
pam_sm_chauthtok PAM_SM_PASSWORD
If a module contains definitions for any of the above functions, it
must supply definitions for all of the functions in the corresponding
management group.
The header file that defines the ANSI prototypes for these functions
is <security/pam_modules.h> . In the case that the module wishes to
offer the functions of a given managment group, it must #define
PAM_SM_XXX, where XXX is one of the above four tokens. These
definitions must occur *prior* to the
#include <security/pam_modules.h> line.
The pam_sm_... functions should be defined to be of type 'PAM_EXTERN int'.
In the case that a module is being compiled with PAM_STATIC #define'd
it should also define a globally accessible structure
_"NAME"_modstruct containing references to each of the functions
defined by the module. (this structure is defined in
<security/pam_modules.h>. "NAME" is the title of the module
(eg. "pam_deny")
If a module wants to be included in the static libpam.a its Makefile
should execute "register_static" with appropriate arguments (in this
directory).
