above is good but I would wonder about the wisdom of having a user root
in LDAP or smbpasswd

Since OP is using LTSP-5 (CentOS-5) he is running recent samba and
therefore, a full set of privileges is described here:
http://samba.org/samba/docs/man/Samba-HOWTO-Collection/rights.html

and I wouldn't recommend having a user 'root' in LDAP unless you
definitely know what you're doing. The machine should have a local root
user. That local root user really doesn't need to be a samba user.

As described in the link above, the user Administrator should be created
with whatever uid, and the well-known RID of 500
