I have 10.6.4 Snow Leopard Server running on a Mac Mini and am having intermittent problems with various iPhones logging into CalDAV calendars. The iPhones are a 3G running iOS 3.1.3 and a 3GS running iOS 4.1.

iCal server works perfectly, with Push, on desktop clients.

The iPhones do work occasionally. Push is still not possible (AFAIK) but 15 minute fetch interval is acceptable for now (when is push coming to iPhones btw?). However, a few times per week, sometimes as many as 5 times in a single day, the iPhone will report "Password Incorrect." This happens on its on, presumably after one of the fetch intervals. Re-entering the password usually works, and is stored correctly for hours or days, but eventually it happens again. Sometimes password is accepted after re-entry but sync will silently stop working, which is even worse than the error popping up.

Each iPhone has 3 CalDAV accounts, one of which is a delegate, one of which is shared by all. The password issue happens with all of them, but far more often with the shared account. The password incorrect prompt does NOT always happen with all of them at once, sometimes just one of the accounts will throw the login error and the others will work for a while.

On the server, iCal has Authentication set to "any method", port 8008 and SSL on, Port 8443

The iPhones connect to CalDAV with SSL on port 8443 using "server" set to

I have deleted the Calendar accounts on the phones repeatedly, hardware reset the phones, deleted all data and set up accounts again. This fixes the problem for a few days but then it comes back.

I don't see much in the iCal server logs, but I might not know what to look for. What should I look for or try next?

Thanks for any help.
