About users and administrators
I think the best way to explain what I mean is using an example.
I installed the Open Source Sugar CRM system.
I need other person can use this system, using their own leads information, but I have to become this person as an administrator, so they can access this system using a username and password.
I don’t want this new administrator can change my password or change their role and so on.
What can I do for that?

Can two persons work as administrator absolutely independent?
One of them will be his/her boss and will check his/her work, but the subordinate cannot check or change any information of his/her boss

Is there any way to not allow to other administrator access the Admin module?

TIA
