Did You Really Secure LDAP – or Just One-Third of It? (Part 1 of 6)
LDAP security is three separate jobs: encrypt the connection, strengthen the authentication method, and secure the account. Enabling LDAPS completes only the first job.

Cleartext or unsigned LDAP simple binds expose reusable passwords. Event IDs 2887 and 2889 identify the affected volume, clients, and accounts before enforcement.
LDAPS and StartTLS can protect LDAP traffic equally when correctly enforced. Protection fails when StartTLS falls back to cleartext or weak TLS remains enabled.
SASL with Kerberos replaces a reusable LDAP password with a short-lived ticket. Signing and channel binding then protect that authentication from tampering and relay.
gMSA and dMSA reduce service-account risk through automatic password management and machine-bound use. They still require protected LDAP transport and least privilege.
A complete LDAP migration starts with auditing, then secures the channel, bind, and account before enforcing signing and channel binding and validating the result.
