you do not have the following permissions ...

Hi folks,

I'm stack with problem 3 days ago, when i want to customize and personalize users.
I create different users and assign different profiles for them but when i want to modify permissions for one user from SUPER to another permissions that i create, i get this error message when i start RTC. "you do not have the following permissions ..."
I tried to add this permissions but there is another permissions to add in error message,so i think that this is the wrong way to solve the problem.

can any one tell me, How can i log to user without SUPER permissions ?

Thanks for you're help
