Thanks for the additional insight into client authentication.
The smart card and IE are set up correctly to prompt for a valid
certificate. I know this because that is how it works when I visit other
web sites on our network that has client authentication implimented. I have
a feeling the problem I am having has something to do with Tomcat not
knowing what to validate clients against.
Does Tomcat use the value in the keystoreFile property to determine what
certificates to validate client against? If so, what entries should be in
the keystore? If not how do I let tomcat know that CA to validate against?
Below is the applicable part of my server.xml
<Connector acceptCount="100"
clientAuth="true"
debug="9"
disableUploadTimeout="true"
enableLookups="true"
keystoreFile="C:\Program Files\Apache Group\Tomcat 5.0\SSL\keystore"
maxProcessors="75"
port="8443"
scheme="https"
secure="true"
sslProtocol="TLS">
</Connector>
Here is the content of the keystore being used for SSL from running keytool
-list. Please let me know if something doesn't look right.

mykey is what I want to validate clients against.
I guess what I am looking for are confiuration steps that I may have missed.
Thanks in advance for your help.

Client Authentication works as follows: You connect to the server, the
server gives you a list with valid certificates. IE looks if it has a
certificate in the list. The next step depends upon your IE settings. If
there is only one matching certificate and you set IE up to automtically
choose one the connection is established. If there are more you get a
window, where you can select the proper certificate. If there are none
you either get a "page cannot be displayed" message (automatic mode) or
you get a window with not certificate to choose.
So if you are using a smartcard you have to somehow tell IE that it
should take a certificate from a smartcard and not its internal
certificate store. I have no idea how this is all working with
smartcards though.
