[galaxy-dev] Using the tool after log in

Hi All, I have local instance of galaxy . I want to make changes in such a way that after log in, user should able to submit any job or run any tool. Log in should be compulsory to run any tool including upload tool. Whenever someone clicks on tool without log in ,it should display message like "You must be logged in <http://192.168.62.51:8089/user/login?webapp=galaxy> to use Galaxy" . Reagrds shashi shekhar
