What do the following lines do in $Self->{CustomerUser} (abbreviated for ease of reading). $Self->{CustomerUser} = { Name => 'Database Source', Module => 'Kernel::System::CustomerUser::DB', CustomerID => 'customer_id', # This line! CustomerValid => 'valid_id', Map => [ [ 'UserCustomerID', 'CustomerID', 'mail', 0, 1, 'var' ], # This line! ], }; What is the difference between CustomerID and UserCustomerID? I find that I can change the value of one and it will not affect the other. Also, I thought that a user's ID was drawn from CustomerID (when the program looks at LDAP to find out what the CustomerID is) but have found that it is drawn from UserCustomerID. Can anyone help me clarify what the role of these two entries are? Thanks, Tyler Hepworth
