[Samba] Creating a machine account manually (EMC, Samba PDC)

[Bryan Ragon]

Greetings,
	I am trying to join a EMC Celerra NS502 CIFS server to our Samba
3.0.21a domain controller.  According to EMC, I was told that we need to
manually create the machine account first.  How is the best way to do this?
We are using an openLDAP backend, using the idealx scripts.  Joining a
windows machine from the computer properties dialog of that machine works
perfectly.

Things I have tried:

Running the NT4 SVRMGR.exe as domain\administrator, file ->Add Computer to
domain

Result:  Dialog box that says "Access is denied"

However when I check the ldap logs the error that cathes my eye:

Jan 26 15:31:44 smokey slapd[14109]: conn=1625 op=58 MOD
dn="uid=boxer$,ou=Computers,dc=zapeng,dc=com"

Now let's suppose I try to run SVRMGR as my own account (who has been
granted seMachineAccountAdd Privileges)

Dialog:  "The user name could not be found"

Samba log:

And checking the ldap logs, it appears that the bind is done anonymously,
which it shouldn't do.
