CAS Authentication with Alfresco

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hello,

I try to configure Alfresco to use a CAS authentication. I modified my web.xml file like this :

<filter>
   <filter-name>Authentication Filter</filter-name>
   <filter-class>edu.yale.its.tp.cas.client.filter.CASFilter</filter-class>
   <init-param>
      <param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>
      <param-value>https://xxxxx:8443/cas/login</param-value>
   </init-param>
   <init-param>
      <param-name>edu.yale.its.tp.cas.client.filter.validateUrl</param-name>
      <param-value>https://xxxxxxx:8443/cas/serviceValidate</param-value>
   </init-param>
   <init-param>
      <param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
      <param-value>localhost:8080</param-value>
   </init-param>
</filter>

<filter-mapping>
   <filter-name>Authentication Filter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And the CAS authentication seems to work : redirection to the CAS login, redirection to alfresco, CAS authentication on the CAS server side but then I get this error :

Did someone get this error and is it possible to "CAS-ify" Alfresco and how ?

Thanks.
