Permission to run a specific SQL job to a user

I added a user to the msdb database and gave him the SQLAgentUserRole but that gave him access to all the jobs, which is not what I wanted. This is the work around I followed....


USE msdb
GO
CREATE PROC dbo.Start_Job_MyJobThatAGroupControls
-- Executes as the database owner, for msdb that is 'sa'
WITH EXECUTE AS OWNER
AS
-- Hardcoding the job name limits this procedure's control
EXEC dbo.sp_start_job @job_name = 'MyProductionJobName'
GO
-- Grant Execute rights to your selected users
GRANT EXECUTE ON Start_Job_MyJobThatAGroupControls TO <usernames>
GO


This way the user will not have direct access to the job MyProductionJobName but through this wrapper sp it can run the job.
