Need user restriction for Open Source script

We are using an open source sript named SugarCRM and need to have the registered users to be restricted so they cannot look at other users data. Only admins should be able to access all of the information. The link to the open source script is: <[login to view URL]> The open source main page is: <[login to view URL]> The other version's page is: <[login to view URL]> In the other version, there is a Team Selling with Data Security which is what we need to adapt to our script. Team selling module can be viewed at: <[login to view URL]> Admin Login login: sugarsales pass: sugar In the top right, there is an Admin link. In the Admin section, click on the Team Management link. What we need is something similar to this module which restricts certain account info to certain users. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
