46. Spring Security FAQ
46.1. General Questions
46.1.1. Will Spring Security take care of all my application security requirements?
46.1.2. Why not just use web.xml security?
46.1.3. What Java and Spring Framework versions are required?
46.1.4. I’m new to Spring Security and I need to build an application that supports CAS single sign-on over HTTPS, while allowing Basic authentication locally for certain URLs, authenticating against multiple back end user information sources (LDAP and JDBC). I’ve copied some configuration files I found but it doesn’t work. What could be wrong?
46.2. Common Problems
46.2.1. When I try to log in, I get an error message that says "Bad Credentials". What’s wrong?
46.2.2. My application goes into an "endless loop" when I try to login, what’s going on?
46.2.3. I get an exception with the message "Access is denied (user is anonymous);". What’s wrong?
46.2.4. Why can I still see a secured page even after I’ve logged out of my application?
46.2.5. I get an exception with the message "An Authentication object was not found in the SecurityContext". What’s wrong?
46.2.6. I can’t get LDAP authentication to work. What’s wrong with my configuration?
46.2.7. Session Management
46.2.8. I’m using Spring Security’s concurrent session control to prevent users from logging in more than once at a time. When I open another browser window after logging in, it doesn’t stop me from logging in again. Why can I log in more than once?
46.2.9. Why does the session Id change when I authenticate through Spring Security?
46.2.10. I’m using Tomcat (or some other servlet container) and have enabled HTTPS for my login page, switching back to HTTP afterwards. It doesn’t work - I just end up back at the login page after authenticating.
46.2.11. I’m not switching between HTTP and HTTPS but my session is still getting lost
46.2.12. I’m trying to use the concurrent session-control support but it won’t let me log back in, even if I’m sure I’ve logged out and haven’t exceeded the allowed sessions.
46.2.13. Spring Security is creating a session somewhere, even though I’ve configured it not to, by setting the create-session attribute to never.
46.2.14. I get a 403 Forbidden when performing a POST
46.2.15. I’m forwarding a request to another URL using the RequestDispatcher, but my security constraints aren’t being applied.
46.2.16. I have added Spring Security’s <global-method-security> element to my application context but if I add security annotations to my Spring MVC controller beans (Struts actions etc.) then they don’t seem to have an effect.
46.2.17. I have a user who has definitely been authenticated, but when I try to access the SecurityContextHolder during some requests, the Authentication is null. Why can’t I see the user information?
46.2.18. The authorize JSP Tag doesn’t respect my method security annotations when using the URL attribute.
