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.

       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).
