See the link to the latest draft of the NTDOM FAQ off my page ( in my
signature ).  To validate logins you will need to define USE_ARCFOUR in
the makefile.

Differences are things like some various pipe functionality as well as
TRUST relationships, etc....  Sorry to be vague but pretty much most of
what you need to run a Samba PDC in a lab is there ( i'm doing the same
thing )

Get the BRANCH_NTDOM version via CVS instruictions in the FAQ.  PDC
support in the main branch does not work.  BRANCH_NTDOM branched from
1.9.18alpha11 but will be rejoining the MAIN branch soon i think.

smbpasswd ( in BRANCH_NTDOM )  has an option -m to add machine
accounts.  Again see the FAQ.
