CAS Authentication with Alfresco

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.

Kevin
