Set permission to show issue to user that they are assigned to that user

[Mahesh Jaiswal]

Is it possible to set permission on user, so that users can see only that issue that they are assigned to that users.

Well, you can set a default security level which includes assignee (Reporter and maybe some other roles should be contained as well). Then you have what you want.

As long as you remember to set the security level (correctly) ;-)
