For network administrators who deal with Active Directory, this is one of those things you'll only need three times in your life, but if you know where to find it when you need it you'll be a hero. Thanks to maarten over at Techlog.nl, here is a post from R.L. Mueller which contains just about every piece of information you'd need abut Active Directory properties, attributes and methods. Nice.

The Microsoft Excel spreadsheets linked below document the Active Directory attributes exposed by the LDAP and WinNT providers. The terms "attribute" and "property" are interchangeable. The name of a property or attribute is similar to the name of a field in a database. The actual value of the attribute is stored in Active Directory. The Active Directory schema can be extended to include additional attributes. The ones documented in the spreadsheets are only the default attributes when Active Directory is installed.
