Several directories can be managed in WorkflowGen. This is particularly useful when the synchronization module is used. For example, one directory can be managed manually in WorkflowGen while another can be synchronized based on an existing directory (e.g. Active Directory). Even if many directories are being used, each username must be unique across the entire system. If multiple directories are being used to synchronize several Active Directory domains, domain names can be prefixed to the user name to eliminate the unique user issue (in the event that user names are identical across domains).
