The information to be logged stems from an _authentificated_ CalDAV or 
ActiveSync session. So maybe the http authentification is not correctly 
passed from rpc.php to Horde?

In prefs_init() hooks I also have requests for user "f", even if I 
prevent that the Horde_History logs an entry with who=="f". So there is 
some other spot that uses the wrong authentification as well.
