I have a ServiceDesk setup that includes two different domains.  What's the easiest way to make it so that users of DomainA are requestors of SiteA inside ServiceDesk and users of DomainB are requestors of SiteB in ServiceDesk?

Is there a way to simply set site to "DomainA" during the import considering there is no AD attribute containing "DomainA" that I can map the field too?

Thanks in advance.
