Hi,

I'm trying to make a simple customer backend. After browsing through documentation I modified the Config.pm file to read:

....
    # CustomerUser
    # (customer user database backend and settings)
    $Self->{CustomerUser} =
    {
        Name => 'Customer Backend',
        Module => 'Kernel::System::CustomerUser::DB',
        Params =>
        {
            # if you want to use an external database, add the
            # required settings
             DSN => 'DBI:Pg:dbname=xxx;host=/var/run/postgresql',
             User => 'xxx',
             Password => 'xxx',
             Table => 'customer',
        },
        # customer uniq id
        CustomerKey = 'mail',
        # customer #
        CustomerID = 'ID',
        #CustomerValid = 'ID',
        CustomerUserListFields => ['firstName', 'middleName', 'lastName', 'mail'],
        CustomerUserSearchFields => ['mail', 'lastName', 'firstName', 'ID'],
        CustomerUserSearchPrefix => '',
        CustomerUserSearchSuffix => '*',
        CustomerUserSearchListLimit => 250,
        CustomerUserPostMasterSearchFields => ['mail'],
        CustomerUserNameFields => ['firstName', 'middleName', 'lastName'],
        CustomerUserEmailUniqCheck => 1,
#        # show now own tickets in customer panel, CompanyTickets
#        CustomerUserExcludePrimaryCustomerID => 0,
#        # generate auto logins
#        AutoLoginCreation => 0,
#        AutoLoginCreationPrefix => 'auto',
#        # admin can change customer preferences
#        AdminSetPreferences => 1,
#        # just a read only source
#        ReadOnly => 1,
        Map => [
            # note: Login, Email and CustomerID needed!
            # var, frontend, storage, shown (1=always,2=lite), required, storage-type, http-link, readonly
            #[ 'UserSalutation', 'Salutation', 'salutation', 1, 0, 'var', '', 0 ],
            [ 'UserFirstname', 'Firstname', 'firstName', 1, 1, 'var', '', 0 ],
            [ 'UserLastname',   'Lastname',   'lastName',   1, 1, 'var', '', 0 ],
            [ 'UserLogin',      'Username',   'mail',       1, 1, 'var', '', 0 ],
            [ 'UserPassword',   'Password',   'pass',          0, 1, 'var', '', 0 ],
            [ 'UserEmail',      'Email',      'mail',       0, 1, 'var', '', 0 ],
#            [ 'UserEmail',      'Email', 'email',           1, 1,
#            'var','$Env{"CGIHandle"}?Action=AgentTicketCompose&ResponseID=1&TicketID=$Data{"TicketID"}&ArticleID=$Data{"ArticleID"}', 0 ],
            [ 'UserCustomerID', 'CustomerID', 'ID', 0, 1, 'var', '', 0 ],
#            [ 'UserCustomerIDs', 'CustomerIDs', 'customer_ids', 1, 0, 'var', '', 0 ],
#           [ 'UserComment',     'Comment',   'comments',    1, 0, 'var', '', 0 ],
            [ 'ValidID',         'Valid',     'ID',    0, 1, 'int', '', 0 ],
        ]
    };

...

The rest of lines before and after this are just the default configuration.

However, when I try to access the index page i get:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, xxx@gmail.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Any help is appreciated. Thank you in advance,
Alexandru Palade.
