NAME
pam_dial_auth - authentication management PAM module for dialups
SYNOPSIS
pam_dial_auth.so.1DESCRIPTION
The
pam_dial_auth module implements
pam_sm_authenticate(3PAM) which
authenticates the user according to the
dialups(5) and
d_passwd(5) files configuration.
Authentication service modules must implement both
pam_sm_authenticate() and
pam_sm_setcred().
pam_sm_setcred() in this
module always returns
PAM_IGNORE.
The value of the
PAM_TTY item is checked against entries in
dialups(5). If there is a match, the user's shell is compared against
entries in
d_passwd(5). If there is a matching entry, the user is
prompted for a password which is validated against the entry found.
The following option may be passed in to this service module:
debug syslog(3C) debugging information at
LOG_DEBUG level.
ERRORS
If
dialups(5) is not present,
PAM_IGNORE is returned. Upon successful
completion of
pam_sm_authenticate(),
PAM_SUCCESS is returned. The
following error codes are returned upon error:
PAM_AUTH_ERR Authentication failure.
PAM_SERVICE_ERR Error in the calling service,
PAM_TTY is not set.
PAM_SYSTEM_ERR System error (
d_passwd(5) is not present).
PAM_USER_UNKNOWN No account is present for
user.

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(7) module is no longer supported. Similar functionality
is provided by
pam_authtok_check(7),
pam_authtok_get(7),
pam_authtok_store(7),
pam_dhkeys(7),
pam_passwd_auth(7),
pam_unix_account(7),
pam_unix_auth(7), and
pam_unix_session(7).
