Additional info:
....the class of configuration error messages could be changed to match the default debug level.
Apparently this was covered with #1345 and in server.c

   if (debug_level == SSSDBG_UNRESOLVED) {
        /* set debug level if any in conf_entry */
        ret = confdb_get_int(ctx->confdb_ctx, conf_entry,
                             CONFDB_SERVICE_DEBUG_LEVEL,
                             SSSDBG_DEFAULT,
                             &debug_level);
