+In cases where a domain coordinator has never used the "Set Domain Configuration"
+utility to create a configuration.db file on a domain's primary library server
+only the following domain defaults: auth_def, auth_arg_def, lang_def
+-- corresponding values are authentication type (internal, krb4, krb5,
+or localauth), initial password or a kerberos realm, language (e.g., en-us) --
+will be available. Values are retrieved from cache (if current), unless the
+optional $ignore_cache arg is true, or from domain's configuration.db (if available),
+or lastly from values in lonTabs/dns_domain,tab, or lonTabs/domain.tab.
