Description of problem:

using curl which uses nss. When I attempt to use pem files with curl (through pycurl) the first pem file I put in as a client-side key is the only one nss will ever use. It won't let me change the in-use key/cert pair.

I think we should hook somewhere around the following condition:

        /* If we previously did client-auth, make sure that the token that
        ** holds the private key still exists, is logged in, hasn't been
        ** removed, etc.
        */
        if (sidOK && !ssl3_ClientAuthTokenPresent(sid)) {
            sidOK = PR_FALSE;
        }

If I return PR_FALSE from ssl3_ClientAuthTokenPresent() in a debugger, it connects fine with unpatched libcurl.  Any chance to invalidate the client authentication for a particular SSL socket?

Created attachment 489418 [details]
less intrusive patch for libcurl

I am not sure if there is a better way to force nss to use the right client cert on the second attempt...

I had done some some downgrades last night and forgot to restore the patch curl builds. Kamil, it does work with your reproducer. Having some problems with the yum test that (404) I'll look into tomorrow.
