คือเมื่อหลังจากลง Jsecurity ใน grials แล้วช่วงแรกก็ทำงานได้ปกติ แม้ว่าจะลอง deploy ลง production ซึ่งเป็น tomcat 6.0 บน ubuntu ก็ดูเหมือนว่าจะไม่มีปัญหาอะไรจนกระทั่งไปเซ็ต SecurityFilters
auth(controller:"*",action:"*"){before={// This just means that the user must be authenticated.// He does not need any particular role or permissionaccessControl{true}}}
แล้วรันบน netbeans & Jetty ก็ยังคงไม่มีปัญหาอะไรแต่เมื่อ deployลง production มันก็ด่ามาทันทีครับ

หลังจากงมอยู่นานก็ค้นพบว่า ตัว tutorial ก็ได้เตือนไว้แล้วว่าจะไม่work ต้องทำตามนี้ด้วย
In Grails 1.1 with the config "jsecurity.legacy.filter.enabled = true" you now must make sure, that you always has a controller, for example localhost:808/myApp won't work. Goto "grails-app/conf/UrlMappings.groovy" an define:
"/"(controller:"public", action:"index")
You now have a secure web application!
หลังจากนั้นทุกอย่างก็ราบรื่นดี นิทานเรื่องนี้สอนให้รู้ว่า อ่าน tutorial ดีๆก่อนจะไปโทษนู่นโทษนี่
