Active Directory File System in Sharepoint 2010

Dear All, What is Active Dir开发者_StackOverflowectory File System in Sharepoint 2010? How can we use it in Sandboxed solutions?

As James says in his comment. There is no thing as AD File System. AD FS is the "official" name of Active Directory.

And no, you can't access AD from a Sandboxed solution.
