5. Click on Server Options and specify server name following either the pattern

Warning: It is not recommended to enable the Use Kerberos v5 for authentication option,

If the account is set correctly, Apple iCal and the mailbox get synchronized.
Now you can set intervals for automatic synchronization:
1. In iCal → Preferences, go to the Accounts tab.
2. On the Account Information tab, select an update interval from the Refresh calendars
menu. The interval should be selected with respect to speed of your internet connection
as well as on update frequency needed.
