Hi Everyone,
I am having difficulties getting a client x509
certificate to be forwarded to Tomcat from Apache using mod_proxy.
From observations and reading a few logs it does seem as though the client x509
certificate is being accepted by Apache. But, when Apache makes an
SSL request to Tomcat (which has clientAuth="want"), it doesn't look like the client x509
certificate is passed during the
ssl handshake.
Is there a reasonable way to see what Apache is doing with the client x509
certificate during its handshake with Tomcat?
Here is the environment I'm working with:
Apache/2.2.3
Tomcat/6.0.29
Java/6.0_23
OpenSSL 0.9.8e
Here is my Apache VirtualHost
SSL config:
<VirtualHost xxx.xxx.xxx.xxx:443>
ServerName xxx
ServerAlias xxx
SSLEngine On
SSLProxyEngine on
ProxyRequests Off
ProxyPreserveHost On
ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel debug
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW
SSLCertificateFile /usr/local/certificates/xxx.crt
SSLCertificateKeyFile /usr/local/certificates/xxx.key
SSLCertificateChainFile /usr/local/certificates/xxx.crt
SSLVerifyClient optional_no_ca
SSLOptions +ExportCertData
CustomLog logs/ssl_request_log \
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
<Proxy *>
AddDefaultCharset Off
Order deny,allow
Allow from all
</Proxy>
ProxyPass / https://xxx.xxx.xxx.xxx:8443/
ProxyPassReverse / https://xxx.xxx.xxx.xxx:8443/
</VirtualHost>
Then here is my Tomcat
SSL Connector:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" address="xxx.xxx.xxx.xxx"
maxThreads="150" scheme="https" secure="true"
keystoreFile="/usr/local/certificates/xxx.jks" keypass="xxx_pwd"
clientAuth="want" sslProtocol="TLSv1" proxyName="xxx.xxx.xxx.xxx" proxyPort="443"
/>
Could there possibly be issues with
SSL Renegotiation?
Could there be problems with the Truststore in our Tomcat instance? (We are using a non-standard Truststore that has partner organization CAs.)
Is there better logging for what is happening internally with Apache for SSL? Like what is happening to the client cert or why it isn't forwarding the
certificate when tomcats asks for one?
Any reasonable assistance would be greatly appreciated.
Thank you for your time.
