Microsoft Introduces a New Registry Setting to Make LDAP Authentication More Secure

As part of its July 2017 Patch Tuesday rollout of security updates, Microsoft is providing a new registry setting to allow administrators to make LDAP authentication more secure over SSL/TLS.

The registry setting is called: LdapEnforceChannelBinding

Its located at: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/NTDS/Parameters

DWORD value: 0 indicates disabled. No channel binding validation is performed. This is the behavior of all servers that have not been updated.

DWORD value: 1 indicates enabled, when supported. All clients that are running on a version of Windows that has been updated to support channel binding tokens (CBT) must provide channel binding information to the server. Clients that are running a version of Windows that has not been updated to support CBT do not have to do so. This is an intermediate option that allows for application compatibility.

DWORD value: 2 indicates enabled, always. All clients must provide channel binding information. The server rejects authentication requests from clients that do not do so.
