You can use standard Shiro realms with the Grails plugin as long as
you declare them as Spring beans. So all you have to do is add
something like this to grails-app/conf/resources.groovy:
beans = {
myRealm(MyJdbcRealm)
}
That's it. The realm will then be used by the plugin's usual
authentication and authorisation code.
Hope that helps,
Peter
