SSO Setting - CAS and Alfresco

Prerequisite:

Alfresco and CAS should use the HTTPS protocol
Let's say, CAS used port 433 and Alfresco 9443
Set Alfresco so it can redirect from port 8080 tobe 9443
Make sure Alfresco and CAS can be accessed with domain name (not recomended with IP Address), in this tutorial use:

Alfresco = http://alfresco.local
CAS = http://cas.softbless.local

1. Add this configuration in alfresco-global.properties file:

#CAS

authentication.chain=cas:external

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

3. Copy commonValues.properties to 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 mycompany folder into C:\Alfresco\tomcat\shared\classes\alfresco\extension\templates\webscripts\org

5. Copy custom-slingshot-application-context.xml to C:\Alfresco\tomcat\shared\classes\alfresco\web-extension folder. Make sure same with below configurations:

<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" />

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

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

</bean>

6. Edit share-config-custom.xml file from 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>

<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>

<id>alfresco</id>

<name>Alfresco - user access</name>

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

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

<identity>user</identity>

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

</endpoint>

</remote>

</config>

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

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

<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>

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

</endpoint>

<endpoint>

<id>alfresco-feed</id>

<name>Alfresco Feed</name>

<description>Alfresco Feed - supports basic HTTP authentication</description>

<basic-auth>true</basic-auth>

<identity>user</identity>

</endpoint>

</remote>

</config>

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

<remote>

<keystore>

<path>alfresco/web-extension/alfresco-system.p12</path>

<type>pkcs12</type>

<password>alfresco-system</password>

</keystore>

<endpoint>

<id>alfresco</id>

<name>Alfresco - user access</name>

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

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

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

</endpoint>

</remote>

</config>

8. Edit relogin.jsp file from 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");

9. Copy alfresco-cas.jar and cas-client-core-3.1.12.jar library into C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\lib folder

10. Copy web.xml file into C:\Alfresco\tomcat\webapps\alfresco\WEB-INF, make sure CAS code same with below configurations:

<filter>

<filter-name>Authentication Filter</filter-name>

<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>

<init-param>

<param-name>casServerLoginUrl</param-name>

</init-param>

</filter>

<filter>

<filter-name>Alfresco CAS Authentication Filter</filter-name>

<filter-class>org.mycompany.cms.authentication.CasAuthenticationFilter</filter-class>

</filter>

11. Copy cas-client-core-3.1.12.jar, logoutCAS.jar, and share-CAS.jar library into C:\Alfresco\tomcat\webapps\share\WEB-INF\lib folder

12. Copy web.xml file into C:\Alfresco\tomcat\webapps\share\WEB-INF, make sure CAS code same with below configurations :

<filter>

<filter-name>CAS Authentication Filter</filter-name>

<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>

<init-param>

<param-name>casServerLoginUrl</param-name>

<param-value>https://cas.softbless.local:443/login</param-value>

</init-param>

<init-param>

<param-name>serverName</param-name>

<param-value>https://alfresco.local:9443</param-value>

</init-param>

</filter>

<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>https://cas.softbless.local:443</param-value>

</init-param>

<init-param>

<param-name>serverName</param-name>

<param-value>https://alfresco.local:9443</param-value>
