samba - Nov 2003 - Question on migrating NT4 shares to Samba 3 (Mandrake)

Hi all,

A quick question on migrating some shares so that they retain proper
user and group permissions from NT4 to Samba 3.

I plan on using ch 31 Migration from NT4 PDC to Samba-3 PDC
(http://de.samba.org/samba/docs/man/NT4Migration.html) as a guide to
perform the migration.  User authentication is by winbind.  This is
already up and running with the machine joined to the domain.

The Samba machine will be a member server rather than a domain
controller.  I have already made a trial run at just moving the
directories/files via rsync which went well.  

Since the machine will not be a domain controller, is there any part of
those instructions that I should not perform or additional instruction
listed elsewhere that I should know about?  One that comes to mind is
should I migrate the users since the net rpc vampire command is for use
on a bdc? 

Thanks for any insight.

Regards to all,
John Little

You will need to unjoin the domain before running the migration process.

So rsync the directories, the leave the domain, then migrate your users.

You need to configure Samba as a Samba BDC. The run the net rpc vampire
process.

I would suggest you migrate to tdbsam. Then, if you want to use LDAP at
the backend, migrate tdbsam to LDAP using:

	pdbedit -i tdbsam -e ldapsam
	pdbedit -g -i tdbsam -e ldapsam

Of course, while migrating tdbsam to ldapsam:
	passdb backend = tdbsam ldapsam

Then remove tdbsam from the above entry after the transfer from tdbsam to
LDAP is complete.
