[Samba] migrate profile from an old server to a new one - SID and ntuser.dat problem

Hi,

my problem is the following:
i am trying to replace an old SUSE 8.2, Samba 2.2
domain controller with a SUSE 9.3 system with samba
3.0 as PDC.
Everything works fine, i can join the new domain, i
replaced the machine and domain sid from the new
server with the old ones. 

But how can  reuse the profiles from the old machine
at the new one? 
If i make a simple remote copy, the settings of the
users are lost, i miss my german keyboard layout and
so on. 
I think that this is a problem regarding the sids of
the users. How can i find out the sids from the old
machine and how can i replace the new ones with the
old ones on the new server?
I tried to do it with " pdbedit -u username -G oldSID"
(i retrieved the old SID from the logs, but i don't
know how to generally get it), but it obviously isn't
changed, because "pdbedit -Lv username" still shows
the old SID.

Thanks for your answers...

I hope you followed the guidance documented in chapter 8 of my book
"Samba-3
by Example, second edition". This book is available from Amazon.Com in 
printed form, or if you want PDF you can obtain it from:

On the old machine:

	cd /var/lib/samba
	rsync -ave ssh profiles newmachine:/var/lib/samba

You must preserve the uids and gids - see chapter 8 referred to above.

[Samba] migrate profile from an old server to a new one - SID and ntuser.dat problem

Hi,

i did the change according to your guideline, but id
don't know how i can preserve the sids and gids of the
users. I am working with exact the same uids and gids
as on the old server, i have changed the sid of the
server (is it a problem the "net getlocalsid" shows
another sid as "net getlocalsid domainname" ?), but
the user sids differ from the user sids from the old
server. Is it a solution to change all sids in each
ntuser.dat to the new value? 
Is it possible that the mistake is that i have to give
the new server a different hostname (routing and
testing reason), or why isn't it enough to change its
sid with "net setlocalsid oldSID?

thank you very much, Christoph

[Samba] migrate profile from an old server to a new one - SID and ntuser.dat problem

Hi, 

thank you for your quick answer...

Sorry, i forgot to tell you that i replaced the sid of
the new server with the sid of the old server. 
But then i have the problem that the user sid (and
gid) are structured like this:
old-sid-from-the-new-server-uid and not
sid-from-the-old-server-uid (the head of the users sid
consists of the sid from the new server, the one that
i replaced with the sid of the old server). So the
Users don't have access rights to their profiles,
because they don't have their original sids.

thank you, Christoph

Chritoph,

Your problem is that while having a new server, by
default
you have a new server SID. The problem is that you
want to
manage users who own SID from your 2.2 server. As we
can't
imagine to lose all users profile, you have to set the
2.2
samba server SID on your 3.0 samba server.

This is a common migration problem.

What you must do is:

1) On Samba 2.2: pick your 2.2 server SID

smbpasswd -X {your_domain}
This will give you a string like this one:
SID for domain mydomain is:
S-1-5-21-1547254743-587533270-2928086249


2) On Samba 3.0: setting 3.0 SID with SID picked on
2.2
Save the current 3.0 SID for eventual recovery needs
net getlocalsied > file_to_save_3.0_SID

Set 2.2 SID on 3.0 PDC like this:
net setlocalsid
S-1-5-21-1547254743-587533270-2928086249

Restart samba and I think things should go better.

Regards,

Pierre

[Samba] migrate profile from an old server to a new one - SID and ntuser.dat problem

Hallo,

i think that my problem is getting smaller, but still
not small enough.
In between, i reinstalled samba. Now i have the
correct sid for the server and domain, and my users
have correct sids (see below), the server-, netbios
and domainname are the same as on the old server, i
preserved the uids and gids of the old server,
actually i copied the passwd, shadow, smbpasswd on the
new server.
But the problem is still: when i log onto a
workstation as a user, his old settings from the old
server are lost. He gets the desktop and whole
settings of the default user. There is no clue in the
logs why the user has (obviously) no access to his
ntuser.dat.
