In a scenario in which an sssd node joined to Active Directory crashed and had to be
rebuilt, restoring key files from backup, other than the obvious files in /etc (for krb5,
sssd, nss etc.) are there other sssd/krb5 persistent databases (/var/lib/sss/db ?) that
would have to be restored (ctdb already handles Samba related databases like secrets.tdb)
in order to recover a system after failure.
What sssd files (if any) other than those in /etc directory would be required to restore a
system that is joined to an AD domain after failure?
