If you're on a Windows box, you're probably going to want to use ADSI. I'd highly recomend picking up "ADSI Scripting for System Administration". All of the examples are VB (not vbscript) but it covers a lot about how to access the metabase. And all you'll really need is Win32::OLE and descriptions of how it's done. I found it very easy to look at it in VB and then write something in Perl. And to be honest, you're not going to find anything easier than using ADSI.

Hope this helps..
