NAME
pam_ldap - PAM module for LDAP-based authentication
SYNOPSIS
pam_ldap.so
[...]
DESCRIPTION
This is a PAM module that uses an
LDAP server to verify user access rights and
credentials.
OPTIONS
use_first_pass
Specifies that the PAM module should use the first
password provided in the authentication stack and not prompt the user
for a password.
try_first_pass
Specifies that the PAM module should use the first
password provided in the authentication stack and if that fails prompt
the user for a password.
nullok
Specifying this option allows users to log in with a blank password.
Normally logins without a password are denied.
ignore_unknown_user
Specifies that the PAM module should return
PAM_IGNORE for users that are not present in the LDAP
directory.
This causes the PAM framework to ignore this module.
ignore_authinfo_unavail
Specifies that the PAM module should return
PAM_IGNORE if it cannot contact the LDAP server.
This causes the PAM framework to ignore this module.
no_warn
Specifies that warning messages should not be propagated to the
PAM application.
use_authtok
This causes the PAM module to use the earlier
provided password when changing the password. The module will not
prompt the user for a new password (it is analogous to
use_first_pass).
debug
This option causes the PAM module to log debugging
information to
syslog(3).
minimum_uid=UID
This option causes the PAM module to ignore the user
if the user id is lower than the specified value. This can be used to
bypass LDAP checks for system users
(e.g. by setting it to 1000).
