When using open directory configure users/groups/locations/resources, with the new memcached caching implementation, what is the best way to handle the situation where -a user tries to invite a specific user email address in iCal, but the user isn't present is OD -so DCS adds that email address to the cache as being invalid -the user adds the user to OD -the user goes back to iCal to re-invite the user At this point, DCS seems to only use the cache entry, which still indicates the address is invalid. What should be done at this point? I've got a separate process that helps manage changes to the server, so I could send a signal to DCS or possibly to the memcached process, but what is the best way to handle this? Of course, the trivial, but extremely heavyweight option is to restart DCS. Eli
