[Samba] NT4 migration errors

Hi
I've setup samba 3.0.14 with the latest idealx scripts on FC3.
Now I have a test lab to migrate from NT4 box which different than the
standalone PDC I have running.

Here's the order I used and my ldap and samba configs are clean
as far as I can tell since I do get a partial migration.
When using 'net rpc vampire -S nt4 -W DOMAIN' it populates the
groups from NT4 and shows the group membership but the users fail to come
over.

Here's what I've done so far. BTW SLES9 server.
[continued below]
>From a clean ldap database I add in the top level ldif:---------------------------------------------------------------------- dn:
dc=kblan,dc=com
o: kblan
objectClass: top
objectClass: dcObject
objectClass: organization
dc: kblan


Then ldapadd the preload ldif to be ready for the NT4 accounts:
--------------------------------------------------------------
dn: cn=admin,dc=kblan,dc=com
objectClass: organizationalRole
cn: admin
description: Directory Manager

dn: ou=People,dc=kblan,dc=com
objectClass: top
objectClass: organizationalUnit
ou:People

dn: ou=Groups,dc=kblan,dc=com
objectClass: top
objectClass: organizationalUnit
ou:Groups

dn: ou=Idmap,dc=kblan,dc=com
objectClass: top
objectClass: organizationalUnit
ou:Idmap

dn: ou=Domains,dc=kblan,dc=com
objectClass: top
objectClass: organizationalUnit
ou:Domains

Then ldapadd the NextFreeUnixID ldif:
-------------------------------------
dn: cn=NextFreeUnixId,dc=kblan,dc=com
objectClass: inetOrgPerson
objectClass: sambaUnixIdPool
uidNumber: 1000
gidNumber: 1000
cn: NextFreeUnixId
sn: NextFreeUnixId


Next add the smbpasswd to secrets.tdb.

Then grab the NT4 SID:
net rpc getsid -S nt4 -W DOMAIN [which succeeds and tdbdump shows it]

Now join the domain:
net rpc join -S nt4 -W DOMAIN -U Administrator%34567 [it joins]

Now we migrate:  I'll show the 'net rpc vampire' first and then
show a slapcat dump of the ldap contents after migrating.
  Comparing to the standalone PDC I setup before,
it seems I'm missing the sambaSamAccount object and all the relevant
 attributes, but I don't know if in fact they are 'supposed' to
existwhen
migrating from NT4 [??].
In any case, I need some help to get the migration done
whatever my mistakes are. I only have 2 groups and a couple of members in
each group. I don't have any local /etc/group entries other than for
services.  [all gid less than 100]
Everything should be in ldap.
Any help is greatly appreciated.
Thanks in advance.

Kevin

It kind of looks like you are working off an old copy of the "Samba3 by
example" book.  Would that be right?

I just checked through some of the output in you post, and think that I am
spot on with that assumption.  You are using:
add user script = /usr/local/sbin/smbldap-useradd -a -m '%u'
In you smb.conf aren't you?
It should be:
add user script = /usr/local/sbin/smbldap-useradd -m '%u'
No *-a* flag.  Samba now takes care of the samba attributes for a user.  You
only need the *-a* flag set if you are adding a user on the command line
using the smbldap-adduser script.  Tah dah! ;-)  John T very kindly pointed
this out to me when I was having problems.  It's one of the small but
infuriatingly important changes made to the book

Without looking too hard at what you are doing, I would suggest that you
follow the online version where you'll see that the smbldap-tools make it
very easy to set up the initial groups by doing the following:
Set up your smb.conf
Go to the smbldap-tools directory and run the configure.pl to configure the
tools.
The tools now pick up most of your settings from the smb.conf
Run the smbldap-populate script as per JHT's example  (the reason that I
suggest this is that it will reduce any human errors made in creating the
initial ldif)

Then follow on as before, checking against the examples shown in the
"samba3
By Example" book online:

Next add the smbpasswd to secrets.tdb.

Then grab the NT4 SID:
net rpc getsid -S nt4 -W DOMAIN [which succeeds and tdbdump shows it]

Now join the domain:
net rpc join -S nt4 -W DOMAIN -U Administrator%34567 [it joins]

Now we migrate:  net rpc vampire -S nt4 -W DOMAIN

I'd be interested to see if you still had problems after that.
