Configuring two way SSL between Client and Weblogic server with Apache proxying the request.

Configure Apache for SSL

Create the certificates using openssl (present in apache_home\bin) using the below steps:

openssl genrsa -des3 -out server.key 1024

openssl req -config ..\conf\openssl.cnf -new -key server.key -out localhost

openssl x509 -req -days 730 -in localhost -signkey server.key -out server.crt

Add the following in the httpd.conf file

<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>

Listen 443
<VirtualHost *:443>
SSLEngine on
SSLCertificateFile “C:\Program Files\Apache Group\Apache2\conf\server.crt”
SSLCertificateKeyFile “C:\Program Files\Apache Group\Apache2\conf\server.key”
SSLCACertificateFile “C:\Documents and Settings\Administrator\Desktop\cert\IntermediateCA.cer”
#SSLLog “C:\Program Files\Apache Group\Apache2\conf\ssl.log”
#SSLLogLevel debug
</VirtualHost>

Configure SSL between Apache and Weblogic Server

Add the following in the Location Directive

SecureProxy ON
TrustedCAFile C:\bea101\wlserver_10.0\server\lib\CertGenCA.pem
RequireSSLHostMatch false

Configure Apache to Request for Client Certificate

Add the following in the Location Directive

SSLVerifyClient optional_no_ca
SSLOptions +ExportCertData

Configure Weblogic Server for 2-way SSL

mydomain> Servers> myserver>Keystores & SSL > Advanced Options
Hostname Verification: None
Two Way Client Cert Behavior: Client Certs Requested but not enforced

Apache_SSL> Domain Wide Security Settings> Realms> myrealm> Authentication Providers> DefaultIdentityAsserter

Trusted Client Principals: provide CN of the Client Certificate
Types: X509

Details:

Use Default User Name Mapper: Checked
Default User Name Mapper Attribute Type: CN
Base64Decoding Required: Checked

Go the security realm and create a user wih the username as CN of the certificate

Add the following in the config.xml
<Server ClientCertProxyEnabled=”true”

Configure the Web Application

The Web Application should require client cert authentication.

Add the following in the web.xml

<context-param>
<param-name>weblogic.httpd.clientCertProxy</param-name>
<param-value>true</param-value>
</context-param>

Add the following in the weblogic.xml

<principal-name> CN of the certificate</principal-name>
