LDAP for Customers

[Kitty]

Hello everyone,

I have the following problem. I enabled authentication via LDAP for Agents and Customers. It's working perfectly fine for the agents, but not for the customers somehow.

OTRS already got the customer data from the AD, but now the customer.pl is broken. When I open this site, this error appears:
Software error:
Got no PreferencesObject! at /opt/otrs/bin/cgi-bin/../../Kernel/System/CustomerUser/LDAP.pm line 36.

I must say, I touched more than just Config.pm, but I didn't save anything. I changed a think in LDAP.pm, but just the number of "customer user search list limit". I already tried to replace LDAP.pm but that didn't change a thing I thing I missed to write something into Config.pm. But the I don't know what, I wrote everything into the Config.pm I could find.

Can someone help me with this problem?

Edit: when I take the settings for the Customers out of the Config.pm, it says "Servererror! Premature end of script headers: customer.pl "

When I use Kernel::System::CustomerAuth::LDAP for that, I don't have the LDAP data from the AD, but customer.pl is still working. If i want to add customer, it says "Not supported for this module!".

If I use Kernel::System::CustomerUser::LDAP, the Userdata is in the Ticketsystem but the customer.pl seems to be broken.
