22.8 About the System Security Services Daemon

The System Security Services Daemon (SSSD) feature provides access on a client system to remote identity and authentication providers. The SSSD acts as an intermediary between local clients and any back-end provider that you configure.

The benefits of configuring SSSD include:

  • Reduced system load

    Clients do not have to contact the identification or authentication servers directly.

  • Offline authentication

    You can configure SSSD to maintain a cache of user identities and credentials.

  • Single sign-on access

    If you configure SSSD to store network credentials, users need only authenticate once per session with the local system to access network resources.

For more information, see the authconfig(8), pam_sss(8), sssd(8), and sssd.conf(5) manual pages and https://fedorahosted.org/sssd/.
