RH423 is designed to train people with RHCE competency on skills required to manage and deploy the Red Hat Directory Server on and for Red Hat Enterprise Linux systems. Gaining an understanding of the basic concepts, configuration, and management of LDAP-based services is central to this course. We will also look at PAM, the Pluggable Authentication Modules system, and how it is integrated with services that require authentication and authorization.

RHCE program provides fundamental skills and knowledge required by this course. Students will integrate standard network clients and services with the directory service in order to take advantage of its capabilites.

RH423 is aimed at senior Red Hat Enterprise Linux system administrators and other IT professionals who need to provide enterprise-wide authentication or information services or who desire training in the management of LDAP-based directory services and customization of Linux authentication using the Red Hat Directory Server.

RH423 requires RHCE-level skills. The RHCE certificate on Red Hat Linux 7.1 or later is recommended but not required. Prerequisite skills can be shown by passing the RHCE Exam in either RH302 or RH300, or by taking RH253 or by possessing comparable skills and knowledge.

Note: Persons should not enroll in RH423 without meeting the above prerequisites. All prospective course participants who do not possess RHCE certification are strongly advised to contact Red Hat Global Learning Services for a skills assessment when they enroll.
