I'm testing the network edition of zimbra. I'm trying to sync a windows mobile 5 dev over the air. It works, but not with ssl! When trying to sync from the device, it complains that the certificate on server is invalid.. In admin's guide somewhere there is a mention that in some cases is necessary to install the ca certificate on device. I assumed the default server ca in zimbra is "ca.pem", which was the one I installed. It still complains that the certificate is invalid.. I really need to use ssl sync.. What can I do to solve this? Is it necessary to generate new certificates??
