Allows Machines to Store Bitlocker keys in AD
'===============================================================================
'
' This script demonstrates the addition of an Access Control Entry (ACE)
' to allow computers to write Trusted Platform Module (TPM)
' recovery information to Active Directory.
'
' This script creates a SELF ACE on the top-level domain object, and
' assumes that inheritance of ACL's from the top-level domain object to
' down-level computer objects are enabled.
