I pulled this from your previous email:

$ grep luke /etc/passwd
luke:unused_by_nt/2000/xp:11021:10513:Luke Kendall,U-CISRA\luke,S-1-5-21-5706737
lukep:unused_by_nt/2000/xp:12898:10513:Luke Paton,U-CISRA\lukep,S-1-5-21-5706737
$ ls -aln ~/.profile
-rwxr-xr-x    1 11021    10513        4327 Aug 30 10:40 /home/luke/.profile

Your uid (11021) and SID (S-1-5-21--76180391-208020174-1021) don't match.
Are you sure this was generated by mkpasswd?  You'll want to double check
this and the difference in ownership and permissions between the files that
vi is working with and those (like .profile) that it's not.  I expect you'll
see a difference there.  It's worth keeping in mind as well that the user
your trying to be in this case is a domain user.  While this isn't a no-no, 
it does come with some extra potential "gotchas" which I alluded to above
and which are covered in the email archives.  But start with these checks
and make sure something here doesn't signal the problem.

Good luck,
