Using the bundled CAS server in uPortal you can use the preferred maven overlay approach to integrating the clearPass feature. There is a patch available to accomplish this, below describes the steps to perform the integration after applying the above patch. By default, the clearPass feature is not activated.

Step 1:

...

Edit the cas deployerConfigContext.xml file

1. Open the deployerConfigContext.file for editing located at ../uportal-portlets-overlay/src/main/webapp/WEB-INF/deployerConfigContext.xml
2. Uncomment the following piece of code AuthenticationMetaDataPopulators property.

                        </list>
                </property>
       
       <!-- 

...

UNCOMMENTED 

...

authenticationMetaDataPopulators 

...

property 

...

-->
       <property name="authenticationMetaDataPopulators">
           <list>
              <bean class="org.jasig.cas3.extensions.clearpass.CacheCredentialsMetaDataPopulator">
                 <constructor-arg index="0" ref="credentialsCache" />
              </bean>
           </list>
        </

...

property>

     </bean>
   
   <bean id="userPasswordDao" class="org.jasig.portal.cas.authentication.handler.support.PortalPersonDirUserPasswordDao"
        p:data-source-ref="dataSource" />

Step 2: Edit the security.properties file

...

## This is the factory that supplies the concrete authentication class
root=org.jasig.portal.security.provider.UnionSecurityContextFactory
#root.cas=org.jasig.portal.security.provider.cas.CasAssertionSecurityContextFactory
root.cas=org.jasig.cas3.extensions.clearpass.integration.uportal.PasswordCachingCasAssertionSecurityContextFactory
root.simple=org.jasig.portal.security.provider.SimpleSecurityContextFactory

.....


## URL of the CAS cleartext password service
##### REPLACE THE URL WITH YOUR CAS SERVER ####
org.jasig.cas3.extensions.clearpass.integration.uportal.PasswordCachingCasAssertionSecurityContextFactory.clearPassCasUrl=http://localhost:8080/cas/clearPass

Step 3: Edit the bundled cas web.xml file

1. Open the web.xml file for editing located at ../uportal-portlets-overlay/cas/src/main.webapp/WEB-INF/web.xml.
2. Uncomment the allowedProxyChains section. (You will probably want to replace the localhost url with your server name)

   Code Block
   lang xml
   <filter>        <filter-name>CAS Validation Filter</filter-name>        <filter-class>org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter</filter-class>        <init-param>            <param-name>casServerUrlPrefix</param-name>            <param-value>http://localhost:8080/cas</param-value>        </init-param>        <init-param>            <param-name>serverName</param-name>            <param-value>http://localhost:8080</param-value>        </init-param>        <init-param>            <param-name>exceptionOnValidationFailure</param-name>            <param-value>false</param-value>        </init-param> <!-- UNCOMMENTED allowedProxyChains -->        <init-param>            <param-name>allowedProxyChains</param-name> <param-value>http://localhost:8080/uPortal/CasProxyServlet</param-value>        </init-param>        <init-param>            <param-name>useSession</param-name>            <param-value>false</param-value>        </init-param>        <init-param>            <param-name>redirectAfterValidation</param-name>            <param-value>false</param-value>        </init-param>    </filter>

Step 4: Redeploy uPortal

ant clean deploy-ear

Step 5: Restart Tomcat
