[Samba] Linux-to-Linux Samba Migration

[Tom Smith]

I'm working on migrating from Mandrake 10.0 to Ubuntu 5.10. The last, 
and probably most important, service to be moved is Samba...

The setup is fairly simple, here is is:

- Mandrake Linux 10.0
- Samba 3.0.10

Here's the "global" Samba configuration of my server:

[global]
        workgroup = <workgroup name>
        server string = <string>
        passdb backend = tdbsam:/etc/samba/passdb.tdb
        passwd program = /usr/bin/passwd %u
        unix password sync = Yes
        time server = Yes
        load printers = No
        add user script = /usr/sbin/useradd -m %u
        delete user script = /usr/sbin/userdel -r %u
        add group script = /usr/sbin/groupadd %g
        delete group script = /usr/sbin/groupdel %g
        add user to group script = /usr/sbin/usermod -G %g %u
        add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null %u
        logon script = scripts\%U.bat
        logon drive = H:
        logon home = \\%N\%U\profile.w98
        domain logons = Yes
        wins support = Yes
        ldap ssl = no
        idmap uid = 15000-20000
        idmap gid = 15000-20000
        admin users = root, tom
        create mask = 0770
        directory mask = 0770
        veto oplock files = /*.xls/

Transferring the files and the associated shares is the easy part. What 
I'm concerned about is getting the domain and user/group information to 
transfer without having to reconfigure all of the workstations or all of 
the user/group accounts on the new server.

I looked to see if I could find such a guide for doing this but wasn't 
able to--not sure if maybe I'm searching for the wrong terms or whatnot.

Any suggestions offered and/or pointers to documentation would be 
greatly appreciated.

Thanks in advance for your help.
