طريقة تسيير المستخدمين

I assume that in the second method, they use one centeral login with admin privilages and then they try to control what the local user can do and what he can't, right?

In other words, they have a single admin account, they then see if the user is an admin or not based on their logic and decide what can he do and what he can't?

I guess that SQL Server provides a great advantages to protect data, and because most of developers don't mastering SQL Server properly they prefer to create they own user tables and do some tedious jobs!

I should write Arabic, sorry about that.

First of all, I am Egyptian, so I can understand and read arabic, I just don't have arabic keyboard as I don't live in Egypt

What I am saying that NO ONE SHOULD EVER write his own authentication system, we are going away of using SQL Authentication because of the same reason, too much trouble, and you can secure against everything, and you get Windows Authentication for free, and it's really a very strong and secure system, so why rebuilding the wheel and having more chances of getting into trouble with the increase of your surface area?

I can list you infinite number of reasons of why the system you listed above is un-secure and has a lot of security issues
