Summary

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. It is also the basis to provide client auditing and policy

services for projects like FreeIPA.

Update Information:

If a user was added to the SSSD BE database without setting a password, the user could ssh to the SSSD configured client and enter any password to gain access. This update resolves this issue so users with no password set are no longer able to login.
