[dev] Support for multiple CustomerAuth modules

[Ralf Becker]

Hello!

I'm just new to OTRS and I'm trying to configure it for our needs. As
our customers should be authenticated using LDAP and internal OTRS
database, I realised that it isn't possible to use multiple
Authentication Modules for customers.

So I've done a very simple AuthModule called
Kernel::System::CustomerAuth::Multiple which uses multiple AuthModules
(like DB, LDAP, Radius, ...) to authenticate customers.


Usage is very simple:

Copy Multiple.pm to Kernel/System/CustomerAuth/Multiple.pm. You'll find
it at http://www.fh-trier.de/~beckerr/OTRS-CustomerAuth/Multiple.pm

To use CustomerAuth::DB and CustomerAuth::LDAP modify your Config.pm
like this:

$Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::Multiple';

$Self->{'Customer::AuthModule::Multiple::Modules'}='Kernel::System::CustomerAuth::DB
Kernel::System::CustomerAuth::LDAP';

So CustomerAuth::Multiple tries to authenticat users using
CustomerAuth::DB first and, if this fails, it trys CustomerAuth::LDAP.
