Lemonldap::NG::Portal::AuthSSL - Perl extension for building Lemonldap::NG
compatible portals with SSL authentication.
=head1 SYNOPSIS
With Lemonldap::NG::Portal::SharedConf, set authentication field to "SSL" in
configuration database.
With Lemonldap::NG::Portal::Simple:
use Lemonldap::NG::Portal::Simple;
my $portal = new Lemonldap::NG::Portal::Simple(
domain => 'example.com',
globalStorage => 'Apache::Session::MySQL',
globalStorageOptions => {
DataSource => 'dbi:mysql:database',
UserName => 'db_user',
Password => 'db_password',
TableName => 'sessions',
},
ldapServer => 'ldap.domaine.com',
securedCookie => 1,
authentication => 'SSL',
# SSLVar: field to search in client certificate
# default: SSL_CLIENT_S_DN_Email the mail address
SSLVar => 'SSL_CLIENT_S_DN_CN',
);
if($portal->process()) {
# Write here the menu with CGI methods. This page is displayed ONLY IF
# the user was not redirected here.
print $portal->header('text/html; charset=utf-8'); # DON'T FORGET THIS (see CGI(3))
print "...";
# or redirect the user to the menu
print $portal->redirect( -uri => 'https://portal/menu');
}
else {
# If the user enters here, IT MEANS THAT YOUR SSL PARAMETERS ARE BAD
print $portal->header('text/html; charset=utf-8'); # DON'T FORGET THIS (see CGI(3))
print "<html><body><h1>Unable to work</h1>";
print "This server isn't well configured. Contact your administrator.";
print "</body></html>";
}
Modify your httpd.conf:
<Location /My/File>
SSLVerifyClient optional # or 'require' if login/password are disabled
SSLOptions +StdEnvVars
</Location>
=head1 DESCRIPTION
This library just overload few methods of Lemonldap::NG::Portal::Simple to use
Apache SSLv3 mechanism: we've just to verify that
C<$ENV{SSL_CLIENT_S_DN_Email}> exists. So remenber to export SSL variables
to CGI.
If SSL is used, authenticationLevel is set to 5. You can use this parameter in
L<Lemonldap::NG::Handler> rules to force users to use certificates in some
applications:
virtualHost1 => {
'default' => '$authenticationLevel > 5 and $uid = "jeff"',
},
Note that you can use Apache SSL environment variables in "exported variables".
See L<Lemonldap::NG::Portal::Simple> for usage and other methods.
