The problem is with second authentication-manager is overriding anthor authentication manager, ie always second authentication manager get executing. Here I am using two custom login pages for two different modules in my project, or tell me how to apply Spring Security for two custom login pages in one project.

Answer 1

You have to give your <authentication-manager> an id attribute not an alias, otherwise the second declaration overrides the first. And then I think you should remove the authentication-manager-ref attribute.

This has been asked on the old spring forum and answered by Luke Taylor (anyone who read Spring security source code will have seen his name a lot) here
