an existing sssd.conf (IPA client for example). Copy the
services section used in sssd.conf, and append 'proxy' to
existing domain section.
Add configuration functionality to allow sssd exclude_users, and
exclude_groups configuration options. These options are only
applicable when scope=all. Refer to man sssd-session-recording(5)
