Change Username column mapping in Microsoft Active Directory Import

Hi

I´m importing user resources from Microsoft Active Directory Import.  Using the default mappings the users were created but the username created is the displayName ad variable. For example the username created is not david.dell but David Dell Gosselin as result.

I cant find the way to change it in order to the username appears as domain account or EmployeID not the displayname.

That would be very useful when massive uploading CI´s to Altiris CMDB.

Any Ideas?

Thanks!
