bill, thankx.  comments below.

> o To create the machine account on the Samba PDC, first create an

workstation trust account.  there is no such thing as a machine account.

...plus any other users (real users) that are domain users.

you need a tab or an "=" not a space.

there are about eight spaces in here.

my favourite part, this.

two.  one.  hang on.  LsaOpenPolicy, then _one_ LsaClose.  yes.  one.

          ^      ^   ^
remove spaces.

...   domain group map entry for "Domain Users".  Check that all entries
in the map files have "=" or tabs as separators between the unix and nt

thanx once again, bill.
