autentication problem

[principiante]

Hello
I have double authentication by LDAP and db but I can not authenticate by db. The error is:

ERROR: OTRS-CGI-96 Perl: 5.16.3 OS: linux Time: Tue Jul 16 09:35:04 2019

Message: Need CustomerID!

RemoteAddress: 10.31.210.77
RequestURI: /otrs/customer.pl?Action=CustomerTicketOverview;Subaction=MyTickets

Traceback (12068):
Module: Kernel::Output::HTML::Layout::CustomerError Line: 4590
Module: Kernel::Modules::CustomerTicketOverview::Run Line: 55
Module: Kernel::System::Web::InterfaceCustomer::Run Line: 1295
Module: /opt/otrs/bin/cgi-bin/customer.pl Line: 40


I have inserted this in config.pl:

$Self->{'AuthModule2'} = 'Kernel::System::Auth::DB';
$Self->{'AuthModule::DB::CryptType2'} = 'crypt';

But it still does not work.
Any ideas?
Thank you.
