NAME
       pam_passwd_auth - authentication module for password

SYNOPSIS
       pam_passwd_auth.so.1 [debug] [nowarn] [server_policy]

DESCRIPTION
       pam_passwd_auth  provides  authentication functionality to the password
       service as implemented by passwd(1). It differs from the  standard  PAM
       authentication  modules  in  its  prompting  behavior. It should be the
       first module on the password service authentication stack.


       The name of the user whose password attributes are to be  updated  must
       be present in the PAM_USER item. This can be accomplished due to a pre‐
       vious call to pam_start(3PAM), or explicitly set by pam_set_item(3PAM).
       Based  on the current user-id and the repository that is to be updated,
       the module determines whether a password is necessary for a  successful
       update  of  the  password  repository, and if so, which password is re‐
       quired.


       The following options can be passed to the module:

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


       nowarn           Turn off warning messages


       server_policy    If the account authority for the user, as specified by
                        PAM_USER,  is  a  server, do not apply the UNIX policy
                        from the passwd entry in the name service switch.


RETURN VALUES
       The following values are returned:

       PAM_BUF_ERR       Memory buffer error


       PAM_IGNORE        Ignore module, not participating in result


       PAM_SUCCESS       Successfully obtains authentication token


       PAM_SYSTEM_ERR    System error

NOTES
       This module relies on the value of the current real UID, this module is
       only safe for MT-applications that don't change UIDs during the call to
       pam_authenticate(3PAM).

HISTORY
       Support for the server_policy option was added in Solaris 9 12/02  (Up‐
       date 2).


       The  pam_authtok_check  module  was  introduced in Solaris 9, and later
       backported to patches for Solaris 8. This included support for the  de‐
       bug  and  nowarn options. Prior to that, these checks were performed in
       the pam_unix module.
