Vedr.: Re: [Samba] Migration from WindowsNT to Samba

Fri Mar 7 13:55:41 GMT 2003

  I was thinking of using rsync, since it has the ability of mapping the
written user-name instead of using UID's. Anyone know how this work on
WindowsNT? I've read, that CygWin hasn't the ACL's properly implemented
yet?
  Does another "cross-platform" exist, that can map between the written
usernames?

ps. I've tried using scopy, but it fails : "Acces denied". It probably is
run as a null account - in log.smbd access is denied as user nobody
pps. I've also tried using a backup program, but this result in an error in
possix_acls.c : Unable to map SID XXXXXXXXXX         <- a lot of numbers

A few other tips:

Make sure you log in to your samba server as root (it sounds completely
natural if you have a unix background when you come from unix, but the
windows admins don't quite expect it), have ACLs enabled in Samba and an
ACLed filesystem installed.

Make sure that you have cloned your NT server using tools like 'net rpc
vampire' so that the SIDs match up.  (you will also need to steal your
current DCs domain SID too).
