I want to use Multi-Domains in Subfolders, not Subdomains

I use WordPress(Multi User) by Subfolders.
And, I want to use Multi-Domains with Domain-Mapping.
Is it possible?
I tried this, But I could not use.
I used dm_sunrise.php(rename to sunrise.php), But Multi-Domains and Domain-Mapping was not worked.

dm_sunrise.php is only for Subdomains ?
Or, I think I mistake settings of DNS .
How to set DNS with using by subfolders?

Please Help !!
