[dev] Customer Backend

We have implemented OTRS with CAS using HTTPBasicAuth and the Customer back end is setup with ldap. We need to create location based reports for tickets. For example we want to create reports that show tickets that have been created in the state of NY in NY City by Queues. I have all the Customer / GIS information in ldap. I need to bring this GIS info for each user somehow into the OTRS customer table so I can create these reports. Since I am using HTTPBasicAuth the users are not imported into the OTRS DB. Is there a way to populate the customer table ? Thanks Chris
