Appendix D: BitLockerTPMSchemaExtension.ldf File Contents

The following is the contents of the BitLockerTPMSchemaExtension.ldf file, which can be used to extend the Active Directory schema from Windows Server 2003 with SP1 to support backing up recovery information for BitLocker and the TPM owner password in Active Directory.

To use this file to extend the schema, you should be familiar with the Ldifde command, which must be run on the domain controller holding the schema operations master role for the forest.

#=====================================================================
#
# Active Directory Domain Services schema extension for 
# BitLocker Drive Encryption and Trusted Platform Module (TPM) recovery
#
# This file contains attributes and class objects that enable
# Windows Server 2003 SP1 and Windows Server 2003 R2 domain controllers
# to store BitLocker and TPM recovery information. 
#
# Change History: 
#   11/2005 - Schema additions for Vista Beta 2 (matches "Longhorn" Server Beta 2)
#    5/2006 - Schema additions and updates for Vista RC1 (matches "Longhorn" Server Beta 3)
#
# NOTE: A schema extension is not necessary if the forest includes an installation
# of Windows Server Codename "Longhorn".
#
# To extend the schema, use the LDIFDE tool on the schema master of the forest.
#
# Sample command:
#   ldifde -i -v -f BitLockerTPMSchemaExtension.ldf -c "DC=X" "DC=nttest,dc=microsoft,dc=com" -k -j .
#
# For more information on LDIFDE tool, see
# http://support.microsoft.com/default.aspx?scid=kb;en-us;237677 
#
# See related guide for setting up Active Directory Domain Services
# for BitLocker and TPM recovery.
