让不同的Symfony 2应用程序使用相同的会话/登录？

Question

I have four Symfony 2.1 applications, I want them to share the same sessions/login system so that logging in one gets you inside the others.

All applications are on the same domain and server, thus they get cookies properly. For some reason they still don't work exchangeable. They all have the same secret property specified in properties.yml .

The problem is that after logging into one, going to other applications require you to login again, and if you do that, then you get logged out of the previous application.

How do I get multiple Symfony 2.1 applications on the same server and domain to work with a single login?

Answer 1

You should configure your session to point to the same storage location, which would be shared for all applications (in case if you use NativeSessionStorage, which is default).

framework:
    session:
        # ...
        save_path: "/your/shared/sessions/path"

By default save_path is set to %kernel.cache_dir%/sessions - which is relative to your applications.
