OK, I am Unix workstation that is a member of an AD domain. A user logs
into me, so I ask winbind to authenticate this user for me. The AD DC
is asked by winbind, 'Hi, do you know this user ?', AD replies 'Yes,
This is its SID-RID', winbind checks the SID to make sure it is the
correct domain, then ignores it. It then either uses the RID to
calculate the Unix ID (if you are using the 'rid' backend), or it asks
AD 'Hello again, can I have the users uidNumber ?' (if the 'ad' backend
is used).

So, on Windows, if you change a username, the new username will
replace the old one. On a Unix machine there isn't the code to do
this ;-)
