[otrs] Problem with 2 customer user backends and invalidated DB users

8 Jul 2014

      Hi,
we have an OTRS 3.3.7  installation with 2 customer user backends (DB and LDAP).
Some users are duplicated on both backends, with different customer ID assigned
on each backend.
If a mail from a duplicated user enters the system, we want to configure OTRS to
use the LDAP backend (so the ticket get the right CustomerID)
So I simply configured the duplicated DB users as "invalid".
The problem is that, If a duplicated user sends an email to the OTRS system,
OTRS continues to attach that mail to the invalid customer user (I can see it because
the DB customer ID is different from the LDAP one) even if the user is marked
as "invalid".

I tried to change the order of the Customer User backends in the config file also
using the numbering:

$Self->{CustomerUser1} = {
    Name => 'LDAP Datasource',
$Self->{CustomerUser2} = {
   Name => 'Customer Database',

But OTRS continues to do the wrong thing.
What do you suggest? Am I doing something wrong?
