Untuk file-file konfigurasi CAS dapat diambil dari https://www.softbless.com/files/alfresco/CAS/deployment.zip

Prerequisite:

• Alfresco dan CAS harus menggunakan protokol HTTPS
• Katakan saja CAS menggunakan port 433 dan Alfresco 9443
• Setting Alfresco agar redirect dari port 8080 ke 9443
• Pastikan Alfresco dan CAS dapat diakses dengan menggunakan domain name (tidak disarankan menggunakan IP Address), pada tutorial di bawah ini:
  • Alfresco = http://alfresco.local
  • CAS = http://cas.softbless.local 

1.       Tambahkan konfigurasi di bawah ini pada alfresco-global.properties:

#CAS

authentication.chain=cas:external

2.       Copy service.xml ke C:\Alfresco\tomcat\shared\classes\alfresco\extension

3.       Copy commonValues.properties ke C:\Alfresco\tomcat\shared\classes\alfresco\extension\messages

# CAS

cas_url=https://cas.softbless.local:443

cas_alfresco_url=https://alfresco.local:9443/alfresco

4.       Copy folder mycompany ke dalam C:\Alfresco\tomcat\shared\classes\alfresco\extension\templates\webscripts\org

5.       Copy custom-slingshot-application-context.xml ke dalam C:\Alfresco\tomcat\shared\classes\alfresco\web-extension. Pastikan berisi seperti di bawah ini:

<!-- Override Logout Controller - to expire Alfresco tickets -->

<bean id="logoutController" class="org.wwarn.cms.authentication.servlet.CASSlingshotLogoutController">

       <property name="cacheSeconds" value="-1" />

       <property name="useExpiresHeader"><value>true</value></property>

       <property name="useCacheControlHeader"><value>true</value></property>

       <property name="connectorService" ref="connector.service" />

       <!-- if blank assumes the same as Share -->

       <property name="casHost"><value>https://cas.softbless.local:443</value></property>

       <property name="casPath"><value>logout</value></property>

   </bean>

6.       Edit file share-config-custom.xml pada C:\Alfresco\tomcat\shared\classes\alfresco\web-extension :

<config evaluator="string-compare" condition="Server">

        <server>

<!-- Enable and adjust the following settings to allow for external access URLs to the

WebScript Framework - to return an externally accessible address for absolute url generation.-->

              <scheme>https</scheme>

              <hostname>alfresco.local</hostname>

              <port>9443</port>

        </server>

    </config>

    <!--Overriding endpoints to reference a remote Alfresco server &ndash;&gt;-->

    <config evaluator="string-compare" condition="Remote">

        <remote>

            <!-- Authenticator implementation used in CAS authentication scenario,

                overrides the default alfresco-ticket authenticator

                <class>org.alfresco.connector.AlfrescoAuthenticator</class> -->

            <authenticator>

                <id>alfresco-ticket</id>

                <name>Alfresco Authenticator</name>

                <description>Alfresco Authenticator</description>

                <class>org.mycompany.cms.authentication.CasAlfrescoAuthenticator</class>

            </authenticator>

            <!-- Connects to an Alfresco instance using ticket-based authentication,

                overrides the default alfresco connector to use ticket authenticator-->

            <connector>

                <id>alfresco</id>

                <name>Alfresco Connector</name>

                <description>Connects to an Alfresco instance using ticket-based authentication</description>

                <class>org.springframework.extensions.webscripts.connector.AlfrescoConnector</class>

                <authenticator-id>alfresco-ticket</authenticator-id>

            </connector>

            <!-- Endpoint using external authentication via CAS-->

            <endpoint>

                <id>alfresco</id>

                <name>Alfresco - user access</name>

                <description>Access to Alfresco Repository WebScripts that require external user authentication

                </description>

                <connector-id>alfresco</connector-id>

                <endpoint-url>https://alfresco.local:9443/alfresco/s</endpoint-url>

                <identity>user</identity>

                <external-auth>true</external-auth>

            </endpoint>

        </remote>

    </config>

7.       Edit file webscript-framework-config-custom.xml pada C:\Alfresco\tomcat\shared\classes\alfresco\web-extension :

<remote>

<endpoint>

              <id>alfresco-noauth</id>

              <name>Alfresco - unauthenticated access</name>

<description>Access to Alfresco Repository WebScripts that do not require authentication</description>

              <connector-id>alfresco</connector-id>

              <endpoint-url>https://alfresco.local:9443/alfresco/s</endpoint-url>

              <identity>none</identity>

       </endpoint>

       <endpoint>

              <id>alfresco</id>

              <name>Alfresco - user access</name>

                <authenticator-id>alfresco-ticket</authenticator-id>

            </endpoint>

        </remote>

    </config>

8.       Edit file relogin.jsp pada C:\Alfresco\tomcat\webapps\alfresco\jsp, tambahkan code di bawah sebelum tanda %> response.addCookie(authCookie);

// deconnection CAS

response.sendRedirect("https://cas.softbless.local:443/logout");

13.   Akses Alfresco dari IE alfresco.local:8080/share, akan redirect ke login CAS. Kemudian login akan muncul dashlet Alfresco.
