I have a 10.5 iCal server running. One user has constant problems. I've made a new account and the issue persists. A lot of 403 errors. People can't always invite him. He can't always invite others. Most invitees show up with "!" by their names. The log is showing that his folder in the CalendarServer can't be found (though sometimes it is) and that he is not enabled in the Calendar SACL, though the main group he belongs to is enabled.
Thoughts and suggestions are appreciated.
