Managing user access in businesses today is something like playing traffic cop in an intersection of a thousand roads. From Web-based applications to homegrown programs, from desktop PCs to the latest crop of smartphones, IT has to be able to control access to every sort of resource while allowing users to access them from anywhere and any platform.
