Hi Tom

When you say users require "Full Access" to the SSL Server, how would you
propose I implement this? I can think of no other way to do this other than
giving these users access to a S&C rule that allows ALL destinations... and
this doesn't make sense to me...?

Your thoughts?

Hi William,

Users must have full access to the server to which they create an SSL
connection because they cannot evaluate the path. If you have a path in
the rule allowing them access, then the connection request fails. Even
the dreaded /* can create this problem.

HTH,
Tom

Hi there

I have some users who are "not allowed" to access the Internet. But
being the nice guy I am I managed to get management to approve the
"opening" of certain sites, such as the medical aid and pension scheme
websites. So to do this I created an S&C rule to allow the necessary
destination sets for all Domain Users. The trick with this is that the
Medical Aid website works just fine, but the Pension website doesn't. I
have now managed to figure out that the problem is related to the fact
that the Pension website is an HTTPS secure site. In fact, any HTTPS
site that I "open", the users keep getting prompted for their
credentials, but any other HTTP website works just fine.

Here are the excerpts from the WEB log (I've removed all the unnecessary
info):
Medical Aid
<clientIP>, WillTest, Mozilla/4.0 etc etc, 11/25/2003, 15:35:57,
w3proxy, <FIREWALL>, -, www.sovhealth.co.za, 196.37.176.210, 80, 2953,
455, 0, http, TCP, GET,
http://www.sovhealth.co.za/web/images/background.gif, image/gif, Inet,
10054, 0x801002, pWEB Protocols, scWEB - Free Sites

Pension Scheme
<clientIP>, WillTest, Mozilla/4.0 etc etc, 11/25/2003, 15:35:58,
w3proxy, <FIREWALL>, -, www.mebmac.co.za, -, 443, 0, 0, 0, SSL-tunnel,
TCP, -, www.mebmac.co.za:443, -, Inet, 12209, 0x0, pWEB Protocols, -

As you can see, the Pension website doesn't find a matching Rule 2 (Site
& Content Rule), and this I cannot understand. Is it possible to declare
HTTP and HTTPS website distinctions in the Destination Sets?

Cheers
William R.
