Jump to: navigation, search

This HOWTO is intended to show you how to change all your LDAP users' passwords in a row:

Put the following script in a text file called passwordchange.pl and make it executable for root. Afterwards just execute it issueing:

sudo perl passwordchange.pl

It will change your LDAP users passwords and create a file in /tmp/users.csv, with the list of users and their passwords.

#!/usr/bin/perl
use strict;
use warnings;
use EBox;
use EBox::UsersAndGroups;

use EBox::Util::Random;
EBox::init();

my $out ="/tmp/users.csv";
{| border=1 class="simple"
! die "ERROR: Can't create or write to file $out\n";
|}

my $users = EBox::Global->modInstance('users');
my @userlist = @{$users->users()   }  ;
foreach my $user (@userlist) {
	my $password;
	$password =  EBox::Util::Random::generate(8);
	print OUT $user->name()." ". $password."\n";
