Requirements:

• grails 1.3.7
• spring-security-core plugin 1.1+
• twitter4j (will be downloaded automatically)

How to install:

grails install-plugin spring-security-core
grails s2-quickstart
grails install-plugin spring-security-twitter
grails s2-init-twitter

Usage:

Add CSS into your view layout:

<link rel="stylesheet" href="${resource(dir:'css',file:'twitter-auth.css')}" />

Put sign-in button:

<twitterAuth:button/>

after clicking this button user will be authenticated through twitter, and redirected to main page (configurable at spring-security-core)

Note that Twitter requires to use some domain name for your app (so 127.0.0.1 isn't working here), to achieve this you can add following line:

127.0.0.1 mytestdomain.local

Configuration

After plugin install you'll get twitter keys stored in your grails-app/conf/Config.groovy, that can be modified later.

Default config:

security {
   twitter {
        language = "en_US"
        button.text = "Login with Twitter"
        popup = false
        autoCreate {
            active = true
            roles = ["ROLE_USER", "ROLE_TWITTER"]
        }
        filter {
            processUrl = "/j_spring_twitter_security_check"
            processPopupUrl = "/twitterAuth/popup"
        }
        domain {
            classname = "TwitterUser"
            connectionPropertyName = "user"
        }
    }
}
