Configuring authentication and authorization in RHEL

You can configure Red Hat Enterprise Linux (RHEL) to authenticate and authorize users to services, such as Red Hat Identity Management (IdM), Active Directory (AD), and LDAP directories. For that, RHEL uses the System Security Services Daemon (SSSD) to communicate to these services. Utilities, such as authselect and sssctl support you in configuring SSSD, Pluggable Authentication Modules (PAM) and the Name Service Switch (NSS).
