I just installed ZCS in latest version : Release 8.5.1.GA.3056.UBUNTU14.64 UBUNTU14_64 FOSS edition.
After installation, by default, only HTTPS was available on Zimbra web.
So, I configured in Zimbra in both mode :
> zmtlsctl both
> zmcontrol restart
Now it's ok, Zimbra web is accessible via both HTTP and HTTPS protocols...
But when I try to login via HTTP, I get the following message: Error - Your browser does not accept cookies. Zimbra Web Client requires a browser that accepts cookies.
Via HTTPS, I do not have this problem, and once I'm logged in HTTPS, I can switcher HTTP without problems (I'm still logged).
=> Why I cannot log me directly via HTTP?
