How to limitate only one report based on roles

Hi All,

Normally, when we create report and put it to the dashboard, all users displays results according to their roles. (Managers can see only their employees and himself etc.)

We want to create one report which shows upcoming employee birthdays for company and expecting to see that every user should see everyone's data. 

Is this possible? I mean normally everyone display the results according to their roles but is it possible to make exception for only one report? How can we do this if it is possible?
