Simple web application with Spring Security: Specification

User Story 1: A user that is not logged in should be forced to authenticate themselves through a login form when they visit a secure page.

NOTE: An application specific login page should be used to enable authentication.

User Story 2: With a valid username/password a user should be able to log in and view the application home page.

Note: Users that have an admin role should be automatically brought to the admin page by default.

User Story 4: Users that visit the root URL should be directed straight to the application home page

User Story 5: Users that fail authentication should be presented with the login page and a reason for the failure.

Note: The username used to login should remain present on the form.

Note: When the failure is because the username does not exist then this should be made clear in the failure message.

User Story 6: When a user is directed to login page, the user should be directed to that page they tried to reach previously.

User Story 7: Create common navigation that all secure pages will contain.
Note: There will be links to home, admin pages and a logout link

User Story 8: Add support for users to logout. When a user logs out they should go back to the login page. A message should inform the user that they have successfully logged out

User Story 9: A user should be only able to log on to the application once. Concurrent sessions should not be allowed. Inform user when login fails due to concurrent login problem.

Security:
1 All JSP pages should not be directly accessible from browser url (except login and index)
– we do this by keeping all our JSP pages under the WEB-INF folder which is not accessible to public
2 All pages on site (except login page) will require users to be authenticated
3 Prevent possible session-fixation attacks

common page elements

User Story 7: Create common navigation that all secure pages will contain.
Note: There will be links to home, admin pages and a logout link.
Note: only admin users should see the admin link on the common navigation.

User Story 10: A common information bar should exist on all secure pages that displays whether the user is logged in or not.

Admin page

    Just wanted to say.. THANK YOU for this excellent series.. I cant wait for you to finish… I found this blog at the right time.. saved me hours of frustration. I have used acegi security before… which provided excellent documentation. While Spring security is more concise and more logical, it’s lack of detailed documentation is extremely frustrating.
    I am implementing a solution using ldap.. using your config as a reference, I got it to work !!
    Thank you again.. look forward to your next blog in the series..

      Khalid,

      Thanks for your comments. I am not sure it will ever finish :), So many things to explore.
      As always, if you wish the series to try and discuss anything in particular leave a comment and I’ll do my best to get round to it.

      Heraclitus.
