I'm in the process of converting from a single Zimbra server to multi-server install. Over the weekend, I installed the proxy component on the main host (so I can move people to new mailbox servers transparently). IMAP, POP, and most of the webmail is fine with a single exception.
Shared calendars for users are coming up with the wrong port/protocol. It is showing up as: http://mail.ourdomain.edu:8080 instead of https://mail.ourdomain.edu (port 443).
I setup a separate proxy server (https://proxy.ourdomain.edu) which is doing the same thing (showing shared calendars as http://mail.ourdomain.edu:8080). Other URLs loaded internally by Zimbra also bring up the wrong port/protocol (for example, Change Password).
Any idea what I did wrong here or how to fix it? I would rather our users only see https://mail.ourdomain.edu (no other ports, and definitely no non-SSL traffic). I've temporarily allowed port 8080 through our firewall but only so our functionality isn't limited while troubleshooting this.
Thanks for any insights anyone may have!
P.S. We're on ZCS 7.2.7 RHEL 5 (RHEL 6 for the stand-alone proxy server and LDAP server).
