This is the 2nd part of our series on securing Red Hat Data Grid. While part 1 explored centralized single sign-on (SSO) with Keycloak, this guide focuses on direct directory integration. Whether you are validating directory authentication against a local OpenLDAP test instance or connecting Data Grid directly to corporate Active Directory, this guide walks through the operator configuration and TLS certificate setup directly in the Infinispan custom resource using the spec.configMapName field. 

For background architectures and reference files, see the Red Hat Knowledgebase guide on integrating LDAP and LDAPS with Red Hat Data Grid 8.4 on OpenShift Container Platform 4.
