What is the recommended way to set up a Task Server that uses an external directory for User/Org information? I don't want to replicate many thousands of records in the Task Server's database, so I want to have it query our own custom DAO (using its own cache mechanism, of course) for anything pertaining to Users and Groups.

The org.jbpm.userprofile package seems to be meant for this kind of thing, but I can't see how to use it with the included TaskService.

Best regards,

Hans
