Comment	> Kronolith is issuing event alarms from user's private calendar to > another user who does not have access to tha calendar. The orange > notification box appears with the alarm title on the screen of > another user. When clicked on event title in the orange box, then the > red notification box appears saying "event not found". > > My system already has the fixed commit from here: > https://github.com/horde/horde/commit/4b482074340bf4e7ddc469d69172c5c0a2c761f8 > > So probably there is something else wrong. > > Jens Wahnes has confirmed this in the kronolith's mail list: > >> I didn't notice this on our test server, but since we updated our main >> server to the latest versions of Horde (including Kronolith 4.2.15), >> this is happening to us as well. >> >> The problem seems to stem from the horde-alarms script being run (a >> cronjob in our case).
