QUESTION POSED ON: 17 May 2002

> We are a financial institution with branches all over country. We have a client-server based application which was initially designed to be implemented in individual branches. Later, with the changing needs of the business, we decided to have a centralized datacenter and all the branches were to connect to one location through the 'net, with the application and the database located at this centralized location.

In order to make the application accessible to all the different branches we deployed the application on Citrix server. In the application, we have a specific role that needs to be granted to the applicaton user; with the grant of this role certain pop-up buttons get enabled in the application. When the application was being used in individual branches, it was fine -- a single user had this role and the role could not create any security hazards, but now different users from different branches connecting to the same application and having the same role is a hazard, as people from one branch have priviledges on the data of another branch.

Can we have a way where in we can still restrict users with same role from accessing certain obejcts??

EXPERT RESPONSE

The best way is to create different roles for each branch. Then assign those roles appropriately. You can still restrict access without roles through a complex combination of triggers and views. But it gets pretty ugly pretty quick. In the end, you would just be simulating the responsibilities of a role. So why not just take this time to redo your roles?
