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.
