Steps in Migration Process

The approximate migration process is described below.

  • You have an NT4 PDC that has the users, groups, policies, and profiles to be migrated.

  • Samba-3 is set up as a domain controller with netlogon share, profile share, and so on. Configure the smb.conf file to function as a BDC: domain master = No .

Procedure35.1.The Account Migration Process

  1. Create a BDC account in the old NT4 domain for the Samba server using NT Server Manager. Samba must not be running.

  2. net rpc join -S NT4PDC -w DOMNAME -U Administrator% passwd

  3. net rpc vampire -S NT4PDC -U administrator% passwd

  4. pdbedit -L

    Note: Did the users migrate?

  5. Now assign each of the UNIX groups to NT groups: (It may be useful to copy this text to a script called

    #### Keep this as a shell script for future re-use
    # First assign well known domain global groups
    net groupmap modify ntgroup="Domain Admins" unixgroup=root
    net groupmap modify ntgroup="Domain Users"  unixgroup=users
    net groupmap modify ntgroup="Domain Guests" unixgroup=nobody
    # Now for our added domain global groups
    net groupmap add ntgroup="Designers" unixgroup=designers type=d
    net groupmap add ntgroup="Engineers" unixgroup=engineers type=d
    net groupmap add ntgroup="QA Team"   unixgroup=qateam    type=d

  6. net groupmap list

    Check that all groups are recognized.

Migrate all the profiles, then migrate all policy files.
