Directory Interface supported on the Financial Application?

I've been trying to locate documentation that states that Directory Intreface is supported on the PeopleSoft Financial application, but have been unsuccessful in finding any. All the documentation lists HRMS, HCM, etc., but never does the documentation specifically list the Financial application. Is it safe to assume that the Financial application is under the "umbrella" of PeopleSoft applications that can utilize the Directory Interface? If this is correct, is there any specific documentation that lists this? Or would it be the same documentation that covers HRMS, HCM, etc.?

Thanks.
