[au-extAuth] 1.0.1 released

This module makes it possible to authenticate against an external Source.
All you need is a program that runs on the server that can be called with the username and password as command line arguments and returns 0 for success and something else for fail.

It can be activated for the frontend and backend separately.
Configuration is done in the settings in the backend.

I hope, this module can be useful for other users as well.

I'm using it, to authenticate against Kerberos (which is run by our AD Windows Server)

For this I've installed on our linux webserver
heimdal-kcm, perl and Authen::Simple::Kerberos

Than I created this little script:

Code:

---

#!/usr/bin/perl

# authentication script for mrbs to authenticate against
# windows active directory with kerberos
# makes use of Authen:Simple:Kerberos
# Code mostly copied from example under:
# http://search.cpan.org/~chansen/Auth...le/Kerberos.pm

# by Marco Tedaldi <tedaldi@hifo.uzh.ch>, 21.7.2011


use strict;
use Authen::Simple::Kerberos;

my $username;
my $password;
my $kerberos = Authen::Simple::Kerberos->new(
    realm => 'MY.KERBEROS.REALM'
);


#get the values from the commandline
$username = shift;
$password = shift;

# exit, if username or password are empty
exit 1 if (!$username || !$password);

if ( $kerberos->authenticate( $username, $password ) )
{
  # on success
  exit 0;
}
else
{
  # authentication failed
  exit 1;
}

MY.KERBEROS.REALM has to be replaced...

and now our users can login to the contao frontend with the same username and password as used on the windows domain.
