This might save someone from pulling out their hair. El Capitan’s Calendar app requires TLSv1.2 handshaking which calendarserver doesn’t provide. The app simply refuses to connect with a misleading error message about not being able to validate username or password.
The workaround is to use a current Apache server to handle the TLSv1.2 portion of the connection and redirect to a plain http connection on the localhost. This killed 3 hours of my day today and I hope someone finds this hard-won knowledge valuable. ./k _______________________________________________ calendarserver-users mailing list calendarserver-users@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/calendarserver-users
