The System Security Services Daemon (SSSD) is a software package originally developed for the Linuxoperating system (OS) that provides a set of daemons to manage access to remote directories and authentication mechanisms.[1] The beginnings of SSSD lie in an open source project named FreeIPA (Identity, Policy and Audit).[2] The purpose of SSSD is to simplify system administration of authenticated and authoriseduser access involving multiple distinct hosts.[3] It is intended to provide single sign-on capabilities to networks based on Unix-like OSs that are similar in effect to the capabilities provided by MicrosoftActive Directory Domain Services to Windows networks.[4]
