pam_ldap

pam_ldap(8)						      System Manager's Manual						       pam_ldap(8)

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 pass-
	      word.

       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  ig-
	      nore 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).
