In the IT world, a computer ''workgroup'' has a problem:  a known user is limited to (and trusted by) only the small few computers used to-date.  This is one of the many ''scalability'' problems in IT is being able to add new computers without having to manually set up the account for that user. Directory Services software and protocols offer a ''centralized'' set-and-forget approach to storing a users account in a central database, against which devices added to the network can directly trust/authenticate.<br />

The government and business world claim to see problems that parallel the workgroup model. For example it could appear to save a lot of administrative overhead if a new hospital was built nearby and could access individual files of the whole country, automatically, not only without manually sending files to the hospital, but also being able to enter the hospital without signing in at a front desk.
