[opencms-dev] OpenCMS secure login to workplace with https and proxypass

[Babak]

Hi

I am using ProxyPass to remove /opencms/opencms/ from my web site URL
and every thing works fine.

Now I need to enable secure login for workplace and already added below 
line to opencms-system.xml :
<workplace-server>https://wjug.ca</workplace-server>

However when I try to login I get below error:
The requested URL /system/login/ was not found on this server.

Is there something I am missing in my configuration ?
has anyone setup secure workplace ?

Thanks
