On my Zimbra 3.0 Server I've modified the Admin-Servers server.xml to run the Admin Server without SSL.
I've a mod_proxy / mod_security Reverse Proxy in front of the Zimbra Webservers (Webmail and Admin Servers). So the Reverse Proxy terminates the SSL connections. This gives me the possibility to filter evil request even if the intruder uses HTTPS. (I working in IT-Security and I'm paranoid ;-)
Now i've upgrade to Zimbra 4.0. It seems to be impossible to run the Admin Server without SSL. I changed the server.xml to run without SSL. Most of the Zimbra Components fail to start, if the Admin Servers runs without SSL. Also the zmprov Command expects an SSL Server.
Is there possibility to run the Admin Server without SSL?
