Revision Note: V1.0 (November 8, 2011): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). The vulnerability could allow elevation of privilege if Active Directory is configured to use LDAP over SSL (LDAPS) and an attacker acquires a revoked certificate that is associated with a valid domain account and then uses that revoked certificate to authenticate to the Active Directory domain. By default, Active Directory is not configured to use LDAP over SSL.
