   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.
   
   Typical usage:
   
 %domdefaults = &get_auth_defaults($target_domain);  %domdefaults = &get_domain_defaults($target_domain);
