You have permitAll to '/**', this opens up everything. I think this should not be there. Also I was only able to get this plugin working with grails.plugin.springsecurity.securityConfigType = "InterceptUrlMap"

After login, it goes to callback url and then to failure url automatically. My app on local server runs on http://127.0.0.1:8080/google-signin and in google console redirect url is "http://127.0.0.1:8080/google-signin/oauth/google/callback". I tried by removing port from it too. The failure url on my browser is coming out to be "http://127.0.0.1:8080/google-signin/oauth/google/error#" which is saying 404. I am new to grails so please let me know do I need to create error and callback routes myself in the app? Please help.

Hey, Many thanks for this example. In this sample demo, after successful authentication, we get redirected to linkOrCreateAccount page. Is there a way to avoid this and auto-logon the user with just google signon. (oAuth). Lets say, after google oAuth success, I want to redirect to a page which is spring-secured. How do I ensure spring security authentication occurs with google oAuth success
