SSSD - System Security Services Daemon

SSSD is a system daemon. Its primary function is to provide access to identity and authentication remote resource through a common framework that can provide caching and offline support to the system. It provides PAM and NSS modules, and in the future will D-BUS based interfaces for extended user information. It provides also a better database to store local users as well as extended user data.

Documentation on configuring SSSD in Fedora or Red Hat Enterprise Linux is available from the RHEL deployment guide. We also have a dedicated Documentation section

Having problems? Check out our troubleshooting page or the "Frequently Asked Questions" page for answers to common issues.
