Course details
Managing users, credentials, and access across a mixed enterprise environment is one of the more complex challenges in Linux administration. This course cuts through that complexity with a practical look at Red Hat Identity Management and its upstream foundation, FreeIPA. Learn how to deploy and administer Red Hat IdM to centralize authentication and policies across your Linux infrastructure, and how to integrate with Active Directory to support hybrid Windows and Linux environments. Find out how to manage certificates and establish a built-in CA for securing services and users. See how to configure VPN access tied to your identity infrastructure for secure remote connectivity. If you're responsible for enterprise Linux identity and access management, or looking to move beyond local accounts and scattered credentials, this course helps give you the tools to build something coherent and production-ready.
