PAM_AUTHTOK_STORE(5)					  PAM_AUTHTOK_STORE(5)

NAME
       pam_authtok_store - password management module

SYNOPSIS
       pam_authtok_store.so.1

DESCRIPTION
       pam_authtok_store provides functionality to the PAM password management
       stack. It provides one function: pam_sm_chauthtok().

       When invoked with flags set to PAM_UPDATE_AUTHTOK, this module  updates
       the authentication token for the user specified by PAM_USER.

       The authentication token PAM_OLDAUTHTOK can be used to authenticate the
       user against repositories that need updating (NIS,  LDAP).  After  suc‐
       cessful	updates, the new authentication token stored in PAM_AUTHTOK is
       the user's valid password.

       This module honors the PAM_REPOSITORY item, which,  if  set,  specifies
       which  repository is to be updated. If PAM_REPOSITORY is unset, it fol‐
       lows the nsswitch.conf(4).

       The following option can be passed to the module:

       debug
			syslog(3C)  debugging  information  at	the  LOG_DEBUG
			level

       server_policy
			If the account authority for the user, as specified by
			PAM_USER, is a server, do not encrypt the  authentica‐
			tion token before updating.

ERRORS
       PAM_SUCCESS
			 Successfully obtains authentication token

       PAM_SYSTEM_ERR
			 Fails	to get username, service name, old password or
			 new password, user name null or  empty,  or  password
			 null.

NOTES
       The interfaces in libpam(3LIB) are MT-Safe only if each	thread	within
       the multi-threaded application uses its own PAM handle.

       The pam_unix(5) module is no longer supported. Similar functionality is
       provided	  by   pam_authtok_check(5),   pam_authtok_get(5),   pam_auth‐
       tok_store(5),  pam_dhkeys(5),  pam_passwd_auth(5), pam_unix_account(5),
       pam_unix_auth(5), and pam_unix_session(5).

       If the PAM_REPOSITORY item_type is set and a service  module  does  not
       recognize  the  type,  the service module does not process any informa‐
       tion, and returns PAM_IGNORE. If the PAM_REPOSITORY  item_type  is  not
       set, a service module performs its default action.
