# value set in the [sssd] section as authoritative for all other
# sections where not explicitly overridden. We changed this so that
# all sections need to set it if they want debug logs set.
# This script can be run to make the new version continue to produce
# the same logs as the old versions did, by explicitly adding
# debug_level to all domains and services that did not have it set
# already.
