Spring Security and Shiro -> How to authenticate a user in Security and pass a token to Shiro

Question

I have two web apps: the first web application is using Spring MVC and Security and makes user authentication in the database. And works very well, thank you.

The second web-app are using Shiro for login user in your database to grant the authorities and etc.

Question: How can I do the login in the first application with Security and pass the token CSRF, or another, from Spring Security pro shiro and use it for your needs?

If you could send me a tutorials or examples of this, I would appreciate.
