I have some problem with CAS and about Single Sign out feature in it. Actually when I entered two application by CAS single sign on it works but when I signout from one of this applications I can enter to the second without login!! it seem that when I sign out from one application I don't sign out from the second one!

I find this note forum.springframework.org/.../t-13868.html by search but I don't beleive that such important issue is neglected by Yale University designer.

If you have any solution of suggestion please inform me
