  • You must edit this property if you want to check CRLs. However, CRL checking is optional, based on site security policy.
  • Edit the value of the LdapClientTlsCRLCheck property only on Teradata Database nodes.
  • If you decide to use TLS protection, edit this property for all mechanisms that have the AuthorizationSupported property set to yes.
  • Edit this property on database nodes and on the Unity. For more information, see Coordinating Mechanism Property Values for Unity.
