It doesn't.

You have basically two options:
1) Implement it from scratch. There are a number of resources that
describe NTLM in detail (basically reverse-engineered since there's no
official documentation), for example:
http://www.innovation.ch/personal/ronald/ntlm.html
2) Implement it via a plugin using the Microsoft SSP interface. Your
starting point would be here:
http://msdn.microsoft.com/en-us/library/aa375512%28VS.85%29.aspx
FWIW, we went for option #2 in our products; the authentication part is
tricky (lots of details) but straightforward in principle (i.e., you
basically call InitializeSecurityContext twice and are done).
