What is Sssd configuration?
The System Security Services Daemon (SSSD) is a service which provides access to different identity and authentication providers. You can configure SSSD to use a native LDAP domain (that is, an LDAP identity provider with LDAP authentication), or an LDAP identity provider with Kerberos authentication.
How does SSSD work with multiple authentication sources?
SSSD can work with multiple identity and authentication sources, which is something pam_ldap cannot do. In flow 4 any response including credentials are cached, so therefore if there is an identity or authentication source that is unavailable, and as long as it is in the LDB cache, things will still work.
Do you need a central account for SSSD?
With SSSD, it is not necessary to maintain both a central account and a local user account for offline authentication. Remote users often have multiple user accounts. For example, to connect to a virtual private network (VPN), remote users have one account for the local system and another account for the VPN system.

In flow 4 any response including credentials are cached, so therefore if there is an identity or authentication source that is unavailable, and as long as it is in the LDB cache, things will still work. What this means is say Active Directory is down, users can still authenticate and work as long as the LDB cache has the data and is not expired.
