In the UK it certainly does. To absolve ourselves of liability for
misuse 'net access must be from an 'identifiable' user. This is part of
our institution-wide security policy.

That's all very well if you have switches which can do DHCP option 82
but most educational institutions have strict budgets to work to, which 
may involve reuse of older kit which was previously used for core 
academic purposes.

I'd say having a login system which identifies the user is considerably
less difficult than maintaining a very extensive database of cable
patches which will inevitably get out of date (think replacement of dead
switches...) within a very short timeframe. 

It's much easier to index an abuse report from an IP directly to a
username, there's less room for argument and error. Functionally, this
is the way most broadband access networks are run anyway,
username/password gets you the PPPoA or PPPoE session.
