[Samba] Upgrading to Samba 3

[M Gill]

Hello

We would like to upgrade our Samba 2.2.7 software on Solaris 8 (Sparc)
to version 3. We are currently using the server as a member server in a
NT4 domain and are using winbindd and have not setup any user/group
mappings ourselves as security is set to DOMAIN and we are using our PDC
to provide authentication.

We have a basic setup (as below). Can we upgrade to V3 and keep the same
settings (smb.conf) and not have to add users to smbpasswd?

Thanks in advance

M Gill
