[TYPO3-english] ig_ldap_sso_auth issue

[hebus.jd at free.fr]

I manage to solve the logout redirect issue :
It doesn't have anything to do with the typo3 plugin but with the CAS configuration : 

In the file Tomcat 6.0\webapps\cas\WEB-INF\cas-servlet.xml, 
In the <bean id="logoutController" class="org.jasig.cas.web.LogoutController" /> part, you have to add the following :
p:followServiceRedirects="true"


For the remaining issue, I'm still stuck.
As a recall: 
-the frontend CAS login form doesn't appear, 
-the normal login form from typo3 redirects me on the cas server login page(so I have to put any login/password on typo3, then a valid login/password on cas)

Any help?
