Installing the IdP OpenID extensions consists of two steps, adding the required JAR files to the IdP installer's lib/ folder, and then modifying web.xml.

Download binary distribution

(TODO)

Build from source

Building the code from source requires Subversion, Maven, and JDK 1.5.

OpenID Library

• Download the library. It can be found in the Shibboleth SVN Repository under "java-openid"
• build the library by running mvn install
• copy the file (target/openid-1.0-SNAPSHOT.jar to the IdP installer's lib/ folder
• copy dependency jars by running mvn dependency:copy-dependencies
• copy the file target/dependency/httpclient-4.0.jar to the IdP installer's lib/ folder

OpenID Extension:

• Download the extension. It can be found in the Shibboleth SVN Repository under "shib-extension/java-idp-openid"
• build the library by running mvn install
• copy the file (target/shibboleth-idp-ext-openid-1.0-SNAPSHOT.jar) to the IdP installer's lib/ folder

Modify web.xml

In the Shibboleth installer package, modify the file src/main/webapp/WEB-INF/web.xml to include the following servlet definition inside the <web-app> element:

<!-- OpenID Provider. -->
<servlet>
    <servlet-name>OpenIDProvider</servlet-name>
    <servlet-class>edu.internet2.middleware.shibboleth.idp.OpenIDProvider</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>OpenIDProvider</servlet-name>
    <url-pattern>/openid/*</url-pattern>
</servlet-mapping>

Finally, reinstall the IdP using the install.sh or install.bat script.
