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).
