Can't not log in alfresco 4.2 Share, using CAS (although /alfresco work OK)

[lacph]

HI everybody,
I'm using Alfresco community 4.2e. I try to config my Alfresco to use CAS for SSO (I used this guide: http://www.softbless.com/en/SSO-Setting-CAS-Alfresco).
Everything look good with /alfresco, but not with /share. please advise.
After I enter my user name and password at CAS's log in page, it rediect back to alfresco share but show error:
…
A server error has occured.

There are a number of reasons why this could have happened:

    You have attempted to access a page that does not exist - check the URL in the address bar.
    You have attempted to access a page that is not accessible to you, such as a private Site dashboard.
    A valid page has been requested but the server was unable to render it due to an internal error - contact your administrator.
….
I try to config session cookie already, but not help (in web.xml):
####
<session-config>
   <tracking-mode>COOKIE</tracking-mode>
      <session-timeout>60</session-timeout>
   </session-config>

You've faced a compatibility problem between spring-webscripts-** jars. Try examinating

at org.mycompany.cms.authentication.CasAlfrescoAuthenticator.authenticate(CasAlfrescoAuthenticator.java:60)
‍‍‍

it calls a method that dose not exist in your version of spring-webscripts-** jar file .

Hello kaynezhang
Thanks for your quick respond, but could you pls advise, how can I fix that. I am a sysAdmin, I do not understand more about programing.
Have a nice day.

[kaynezhang]

The jar package you download from http://www.softbless.com/en/SSO-Setting-CAS-Alfresco  is not compatibile with spring-webscripts-** jars in your alfresco version
You need to download source code from softbless and modify it according your spring-webscripts-** jars and  then rebuild it.
