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:
<!--
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 share-config-custom.xml file from C:\Alfresco\tomcat\shared\classes\alfresco\web-extension :
<config
evaluator="string-compare" condition="Server">
<server>
<!--

Framework - to return an externally accessible
address for absolute url generation.-->
<scheme>https</scheme>
<hostname>alfresco.local</hostname>
<port>9443</port>
</server>
</config>
<!--Overriding

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

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:
