Comment	> I have a customer using Horde with iCAL4OL to sync calendars and > contacts between users. After upgrading to 5.2.1 from 5.1.6 they > cannot use iCAL4OL anymore, because there seems to be a problem with > the authentication. iCAL4OL starts a CalDAV sync with the given > credentials, then it gets disconnected and cannot authenticate again, > because it tries to use the previous session which is not available > any longer. > > I did have a quick check with the developer of iCAL4OL who found out, > that if iCAL4OL sends the login credentials each time the server asks > for them (new connection / new ssl-handshake) it works fine.
