Hi G40, I am a bit confused from your description, I do not know what you mean by "common access cards" and what you mean by forcing them. Also I do not understand where is your python proxy, is it on the server or on the client ? I have a suspicion that you are mixing the client and the server. Is the configuration that you use a web browser with a certificate to access a URL on the server, the URL is served by a python script that makes another HTTP call to the same server ? If this is the case, it can't work, because the certificate cannot be delegated from the server-side script to another server-side script. The reason is that it is not the certificate alone what is needed to make an authentication to an SSL server, also the private key is needed. Cheers Martin Dne 18.1.2011 16:36, g f napsal(a):
Hello Martin,
thanks for the reply.
I have those directives already and it all works until I add:
/SSLVerifyClient *require*/
I changed this directive to /*optional*/ and it seems to work now, though I am not so confidant in this configuration.
I wonder if there is a way to pass the client cert through to the python proxy?
Thanks,
G40

Hi G40,
the "SSLVerifyClient require" requires that the client presents a certificate.
You have to configure also the list of Certification Authorities that
the server accepts by the following directives:
SSLCACertificatePath /etc/ssl/certs/
or
SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt
If the client certificate is not signed by a root CA, but by some intermediate CA,
which may be in turn signed by another intermediate CA, etc., you need also
to set the value for SSLVerifyDepth to the highest length of the certificate chain
that the client may provide.
The "Allow" directives play no role in this, because the error you have got
happened during the SSL handshake, which is sooner than the Allow directives are applied.

Hello all,
I have a debian os running Apache 2.2.16(debian) along with tomcat 6.0.29. I use mod_jk as well as mod_auth_kerb module for apache. Apache and the modules are debian repository packages.
I recently attempted to activate common access cards and if I just activate them but do not force them it works great.
Once I force access cards, I get the following error and my web-apps break.
Force access cards via:
|SSLVerifyClient require
SSLVerifyDepth 2|
info level logging error.log:
[Tue Jan 18 14:47:07 2011] [info] [client 127.0.1.1] SSL library error 1 in handshake (server myserver.xxx.xxx.xxx:443)
[Tue Jan 18 14:47:07 2011] [info] SSL Library Error: 336105671 error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate No CAs known to server for verification?
The web-app that throws this message uses a python proxy to make an ajax call to a different web context (we do this to avoid the cross site error).
I believe what is happening is that the python script [client 127.0.1.1] is making the request to apache without valid client certs and hence is getting denied.
I have a directive in apache2_home/sites-enabled/default-ssl conf file that I had hoped would solve this issue(however it does not).
directive in default-ssl conf file
|Allow from localhost
Allow from 127.0.1.1
Allow from 127.0.0.1
|Is there a solution to this issue?
Perhaps a way to not require client cert from localhost?
Thanks for any advice, much appreciated!
Cheers,
G40
