Hi Andrew,

I think it will be why you are seeing that error.  There is a check in the 
default JSP which displays that message if the connection isn't secure:

<c:if test="${not pageContext.request.secure}">
<div class="errors">
<p>You are currently accessing CAS over a non-secure connection.  Single Sign 
on WILL NOT WORK.  In order to have single sign on work, you MUST log in over 
HTTPS.</p>
</div>
</c:if>

I have a question for you re the SSL offload though.  We're deploying the same 
architecture you describe and I'm having problems today where-by CAS (for some 
reason I've yet to get to the bottom of) is performing a redirect back to the 
login page.  The redirect is over HTTP which our load balancers are not 
configured to support and we get and error.  So I wanted to ask how your 
architecture would manage a 302 redirect response from CAS back to itself which 
would have a Location header URL starting http://<http:///> and not 
https://.<https://./>

Thanks,
Matt

Subject: [cas-user] SSL offload and HTTPS warning?


We've updated our CAS to 3.4.10, now in the default login view we get a warning 
"You are currently accessing CAS over a non-secure connection. Single Sign on 
WILL NOT WORK. In order to have single sign on work, you MUST log in over 
HTTPS." But in fact from the client we are connecting via HTTPS, but we have 
the SSL offloaded by the load balancer so the connection from the load balancer 
to CAS isn't HTTPS.

Is this the cause of the error? We don't have that warning in the JSP of our 
custom views and we have no problems with them.
