Subject Re: Demand CLIENT-CERT only on certain pages but demand SSL in all pages
Date Fri, 09 Oct 2015 07:21:31 GMT
@Mark Thomas:

I have been going through the documentation on

https://docs.oracle.com/cd/E19798-01/821-1841/bncbk/index.html

trying to come up with a set of security constraints that allow me to force
SSL without asking for a client certificate except on a single login page,
but there is nothing there suggesting a configuration where I can force SSL
without asking for a client certificate: Once I set the CONFIDENTIAL
transport guarantee and the CLIENT-CERT auth method I will be asked for a
client cert when I land on a SSL page, no matter what.

I think I am getting something wrong. Please, can you be more specific on
the solution you suggest?
