Redirect http to https
N.B. If you just want to force authentication to occur over https, use zmtlsctl.
Edit Login.jps
In the file /opt/zimbra/tomcat/webapps/zimbra/public/Login.jsp, comment out this statement:
qs = emptyQs? "?initMode=" + currentProto: qs + "&initMode=" + currentProto;
So that it looks like this:
//qs = emptyQs? "?initMode=" + currentProto: qs + "&initMode=" + //currentProto;
Set mixed mode
su - zimbra zmtlsctl mixed tomcat restart
