[Samba] Migrate NT PDC to SAMBA PDC

[blob]

Hi all,

I'm trying to migrate NT PDC server to Samba PDC.
and now i use samba 3.0.0beta2.
I looks the migration steps from samba-howto-collection.pdf or
in http://us2.samba.org/samba/ftp/cvs_current/docs/htmldocs/nt4migration.html,
and it's not works well. The step is :

********
The approximate migration process is described below. 
" You will have an NT4 PDC that has the users, groups, policies and profiles 
to be migrated 
" Samba-3 set up as a DC with netlogon share, profile share, etc. 

The Account Migration Process 
1. Create a BDC account for the samba server using NT Server Manager 
   a) Samba must NOT be running 
2. rpcclient NT4PDC -U Administrator%passwd 
   a) lsaquery 
   b) Note the SID returned 
3. net getsid -S NT4PDC -w DOMNAME -U Administrator%passwd 
   a) Note the SID 
4. net getlocalsid 
   a) Note the SID, now check that all three SIDS reported are the same! 
5. net rpc join -S NT4PDC -w DOMNAME -U Administrator%passwd 
6. net rpc vampire -S NT4PDC -U administrator%passwd 
7. pdbedit -L 
   a) Note - did the users migrate? 
8. initGrps.sh DOMNAME 
9. net groupmap list a) Now check that all groups are recognised 
10. net rpc vampire -S NT4PDC -U administrator%passwd 
11. pdbedit -Lv 
   a) Note - check that all group membership has been migrated 
Now it is time to migrate all the profiles, then migrate all policy files.
More later.
******************

The problem is:
1) when using command "net rpc vampire..." (step 6), i found some message 
bellow:
[2003/07/07 16:25:59, 1] utils/net_rpc_samsync.c:fetch_account_info(454)
  SAM Account for beda failed to be updated in the passdb!
2) In step 7 & 11, i found some message like this :
build_sam_account: smbpasswd database is corrupt!  username lain with uid 2 is 
not in unix passwd database!
3) I can't found file "initGrps.sh" (step 8)

Can anybody tell me what is the problem?
is there anybody doing this with successfull?

Best Regards
