Applies to

  • ONTAP 9 (all versions)
  • LDAP integration using Active Directory as LDAP server
  • LDAPS (LDAP over SSL/TLS) configurations

Answer

The removal of the Client Authentication (id‑kp‑clientAuth) identifier from SSL/TLS certificates will not affect ONTAP LDAP connectivity or configuration when Active Directory is used as the LDAP server.

  • ONTAP LDAP/LDAPS configurations do not rely on client certificates or mutual authentication.
  • Active Directory Domain Controllers only require a server certificate to authenticate themselves to clients during LDAPS communication.

Because ONTAP does not use client certificates for LDAP/LDAPS and no component in the LDAP workflow depends on the id‑kp‑clientAuth identifier, this change will not impact existing LDAP connectivity or configuration.
