Please point me to the errors I made in the chapter you took this from so I
can fix it. I really do apologize for leading you astray if in any place I
recommended using the ou=Computers in the Samba-3 by Example (Samba-Guide)
It is well known that Samba-3 with LDAP requires the use of nss_ldap to
resolve UIDs and GIDs for machine accounts as well as for users and groups.
There are two solutions to being able to resolve them correctly. The first is
to put all machine accounts in ou=Users (that is the simple and efficient
solution), the other is to set the search path for nss_base_passwd and
nss_base_shadow to point to the level of your directory from which both Users
and Machines can be found by recursively searching the directory. In this
case you must also use the "?sub" parameter in place of the "?one" parameter.

As it should. Again, apologies if I misled you in any way. Please point me to
the section in Chapter 6 where the errors are so I can fix them.
PS: If you would care to suggest better wording please give me your
documentation patch - I really do appreciate contributions. :)

This is a VERY well known issue.
