[Samba] Migrating (vampire) from NT4 to samba 3.5.7

[Veiko Kukk]

Hi,

I'm trying to prepare migration from NT4 server to samba with ldap 
backend. For testing and simulating I have prepared one NT4 server, one 
Centos 5.5 samba server and now I have almost working setup for 
vampiring users and groups.

Using following packages:
samba3.i386		3.5.7-43.el5
samba3-cifsmount.i386	3.5.7-43.el5
samba3-client.i386	3.5.7-43.el5
samba3-doc.i386		3.5.7-43.el5
samba3-utils.i386       3.5.7-43.el5
smbldap-tools.noarch	0.9.5-2.el5.rf
openldap.i386		2.3.43-12.el5_5.3
openldap-clients.i386   2.3.43-12.el5_5.3
openldap-servers.i386   2.3.43-12.el5_5.3

On NT4 PDC I have entered only some sample users and groups.
I'm worried about error messages during vampiring.

1) Why and what does mean "ldapsam_update_sam_account: No user to modify!"?
2)It creates EKRPTESTSERV$ machine account, but next complains that user 
EKRPTESTSERV_ doesn't exist. Why $ is being replaced by _? Same with 
second machineaccount which the samba machine and what are consequences 
of that error? Is it the same bug?

3) There is also group Administrators which contains user Administrator 
and group Domain Admins on NT4 PDC, but those do not get vampired... on 
linux server, group Administrators is empty: Administrators:*:544:

Following is vampire log:
net rpc vampire -S EKRPTESTSERV -U Administrator
