Course Content

Red Hat® Enterprise Directory Services and Authentication is an intensive course designed to train senior system administrators in the skills required to manage and deploy the Red Hat Directory Server on and for Red Hat Enterprise Linux® systems.

This course also covers cross-platform integration of directory services in order to provide authentication or information services across the enterprise. In addition, students will gain an understanding of the basic concepts, configuration, and management of lightweight directory access protocol (LDAP)-based services. This course also explores the Pluggable Authentication Modules (PAM) system, and how it integrates with services that require authentication.

This course can also help prepare current RHCEs for the Red Hat Certificate of Expertise in Directory Services and Authentication Exam (EX423).
