[cas-user] Cas 4 and SAML problems (NULLPOINTER EXCEPTION on remoteGetUser() in my login page)

[Gianluca Diodato]

Hi all,
I followed this 
tutorial 
https://wiki.jasig.org/display/CASC/Saml11TicketValidationFilter+Example 
but don't work.
So I followed this one 
https://wiki.jasig.org/display/CASUM/SAML+Support+in+CAS+4.
I changed my files in cas server as attached and configuration of my 
web.xml in my java client 3.3.3 with all jar for saml added:

When i launch my web app i can login in cas server but when redirect go in 
my web app again i don't have username (is null) and when in my index.jsp 
page i use method "request.getRemoteUser()" i have nullPointer exception..

What wrong? I introduced saml because i must any attributes like name, 
lastname, address and so back from cas server (info into cas server DB 
users table).

Best
