ChangeAuditor is installed in a child domain and is unable to enumerate attributes from other domains.
ChangeAuditor should be installed on the top level domain, however if this is not possible you can add Domain or Enterprise credentials via the Options tab. You must select "save selection" so that the credentials will not be lost.
Depending on the security and settings of your environment this maybe enough to allow ChangeAuditor to function in the child domain.
If it is not, you must install Change Auditor in the top level domain or another option is to install in the other domains using the Multi-Forest configuration where then those Coordinators can all report back to the main database.
