User authentication problem

User authentication problem

I had developed an application using zoho crm.

In that application i made 4 forms.

In one form i.e Salesman Data , I want to give user authentication (i.e 1 Salesman can only see his report not others).

There will be 20 salesman like this.

And There is one form which can be seen by only 5 person team.


Please tell me how to achieve this.
