The AD fields scanned by Lansweeper are hard coded into the Lansweeper Server service, but you could potentially use OPENQUERY to retrieve additional AD information directly from a report. We can't really provide instructions or support for this, but more information on OPENQUERY can be found in
this article on the Microsoft website for instance. Your database will need to be installed under SQL Server for this.
Built-in scanning of additional AD information is on the wish list as well, though we do not have a release date for this feature.
