samba - Feb 2006 - Upgraded from 3.0.9 -> 3.0.21b - Now adding machines a problem

I recently upgraded my samba pdc from version 3.0.9 to version 3.0.21b 
to try and fix a browse issue with Windows 2003 Server and linux samba 
servers.  The browse issue was fixed, but now I am having problems 
adding machines to the network.  I run slackware 10.0 linux with an 
openldap backend which has worked fine until now.  I also upgraded the 
samba tools from idealx.org to the latest version.  First when I went to 
add a machine it would bomb out and when I would check the ldap 
directory I noticed it had the posix machine info but not the samba 
machine info.  To add the machine I am using the command

add machine script = /usr/local/sbin/smbldap-useradd -t 0 -w '%u'

in my smb.conf as specified in the example.  I then looked at the 
smbldap-useradd script and realized that the add_samba_machine call from 
the tools.pm file was never getting called anywhere in the scripts so 
maybe this is incorrect but I added the following to the smbldap-useradd 
script:

   if (defined($Options{'w'})) {
       if (!add_samba_machine($userName,$userUidNumber,$Options{'t'})) {
         die "$0: error while adding samba account\n";
         }
   }

right under the following:
# MACHINE ACCOUNT
if (defined($Options{'w'}) or defined($Options{'i'})) {

   #print "About to create machine $userName:\n";

   if (!add_posix_machine 
($userName,$userUidNumber,$userGidNumber,$Options{'t'})) {
     die "$0: error while adding posix account\n";
   }

so that the rest of the ldap info was getting filled in.  It still would 
bomb out on me with the error "The user name could not be found" but
it
did make a difference.  Leaving the new ldap entry alone I would then 
try and add the machine again and it would work so I am not sure what is 
wrong.  I checked the machine entry in ldap before and after and nothing 
much seems to have changed.  I checked the samba logs and the user 
adding to the domain comes back as authenticated so I am at a loss as to 
why it would fail the first time and not the second.

Now most likely I am doing something else wrong as I can't imagine I 
should have to change the scripts but I haven't come across what it is. 
  Has anyone seen this behavior before?

Any help is greatly appreciated thanks.

Dan,
