I don't have an answer for you, a couple thoughts though, are you using an SSL
cache that may be caching the info? I think there is a cache directive in mod
ssl. Or is there software on the client for handling the smart card that could
be set or configured to renegotiate?

Subject: Re: [users@httpd] Client Auth Retries
This behavior is puzzling.
*Once the browser goes to the “mistake” page, it won’t renegotiate
the SSL connection with the smart card despite
- No open https connections to the server
- The behavior persists across a server restart
- The behavior persists across a “clear cache” on the client browser (Chrome)
The only way to force it to use the smart card auth appears to be quitting and
restarting
the browser.

I’m trying to set up client authentication using smart cards and be reasonably

auth failures. A typical failure mode is that the user doesn’t have the card

should send them to a warning page, then let them retry.
The relevant config file for the top level:
SSLVerifyClient optional
RewriteEngine On
RewriteCond %{SSL:SSL_CLIENT_VERIFY} !^SUCCESS
RewriteRule .* /mistake/index.html [L]
<Directory /var/www/html/mistake>
SSLVerifyClient none
</Directory>
Client auth is optional, but if it fails they see the informational
page telling them to use a smart card, in a directory
without smart card auth required.
This successfully rewrites to the informational page when they
don’t have the smart card inserted. The first time in If client auth fails for
some reason they see the error page, and if they do have
the card and authenticate, they see the expected content.
But if they see the error page, then insert the card, and then
try to go to the https://myhost/content, they continue to
see the error page. It seems as if the HTTPS connection
is not being renegotiated or that the SSL_CLIENT_VERIFY
is not being reset to SUCCESS on retry. Or is there a
better way to do this?
