Weceem Spring Security Plugin for Grails
Security in the Weceem plugin is completely decoupled so that you can plug in whatever security mechanism you are using, and this plugin uses this mechanism to have your user information supplied to Weceem from Spring Security Core. You can configure the property mappings from your user domain classes to the user object properties available at runtime.
It is now compatible with Grails 2.4.x, current released version: 1.3 release notes
Full documentation about Weceem plugin is available on the GitHub
