<title>DESCRIPTION</title>
<para>
<command>SSSD</command> provides a set of daemons to manage access to remote
directories and authentication mechanisms. It provides an NSS and
PAM interface toward the system and a pluggable backend system to
connect to multiple different account sources as well as D-Bus
interface. It is also the basis to provide client auditing and
policy services for projects like FreeIPA. It provides a more robust database
to store local users as well as extended user data.
