[horde] pref hooks

Since I have found out that four out of these five invocations
do not provide a sensible argument (and do not expect a sensible
answer), my functions look thusly:
   function _prefs_hook_fullname($user=NULL)
   { $name = empty($user) ? '' : knu_user_data ('cn', $user);
     knu_debug(__LINE__, '_prefs_hook_fullname', array($user), NULL, $name);
     return $name;
   }
where knu_user_data retrieves the desired detail from the session data
(and stores the user-related data there, on its 1st invocation), and
knu_debug logs a line in the Horde log, if so desired. (All locally defined
function names have that "knu_" prefix in order to avoid name clashes.)

I've got no idea -- just worked around this glitch.


Good luck,
