pam_dial_auth(5)

NAME

     pam_dial_auth - authentication  management  PAM  module  for
     dialups

SYNOPSIS

     /usr/lib/security/pam_dial_auth.so.1

DESCRIPTION

     The dialup PAM module, /usr/lib/security/pam_dial_auth.so.1,
     authenticates  a  user  according  to  the  /etc/dialups and
     /etc/d_passwd files. Only  pam_sm_authenticate()  is  imple-
     mented  within this module. pam_sm_setcred() is a null func-
     tion. /usr/lib/security/pam_dial_auth.so.1 is designed to be
     stacked            immediately           below           the
     /usr/lib/security/pam_unix.so.1 module for  the  login  ser-
     vice.

     pam_sm_authenticate() performs authentication only  if  both
     the  /etc/dialups and  /etc/d_passwd files exist. The user's
     terminal line is checked against entries in the /etc/dialups
     file.  If  there  is  a  match, the user's shell is compared
     against entries in the /etc/d_passwd file.  If  there  is  a
     matching entry, the user is prompted for a password which is
     validated against the entry in the  /etc/d_passwd  file.  If
     the  passwords match, the user is authenticated. The follow-
     ing option may be passed in to this service module:

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

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 might not be supported  in  a  future
     release.    Similar    functionality    is    provided    by
     pam_authtok_check(5),                    pam_authtok_get(5),
     pam_authtok_store(5),   pam_dhkeys(5),   pam_passwd_auth(5),
     pam_unix_account(5),          pam_unix_auth(5),          and
     pam_unix_session(5).
