Samba4 Development
Introduction
This wiki page will be used to track the integration effort of Samba 4 into SME 9+
G.Zartman Note: At this point, I'm just going to randomly ramble on this wiki page as I work on Samba 4. Once I get some workable pieces, I'll go back and format this page so that it makes more sense.
Samba 4 Packages
General Development Notes
Template Fragments to Modify
/etc/smb.conf
Complete rewrite of all template fragments

smb.conf Considerations
Server Services: This parameter is not very well documented, but from what I could find thefollow services can be provided by the Samba daemon: s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, ntp_signd, kcc, dnsupdate, dns, smb, nmb, winbind. The default for this parameter is: server services = s3fs rpc nbt wrepl ldap cldap kdc drepl winbind ntp_signd kcc dnsupdate dns. Services can be added/remove from the default by a +/- and the service to add/remove. Example server services = -s3fs (remove) +smb (add). Note that the smb, nmb, and windbind services are services equivalent to the older, Samba 3, type services (stand alone daemons). Of specific interest to SME 9 may be the use of the nmb service for WINS support. As we begin testing we may need to enable this service and possibly smb for simple share access.
Server Role:' Samba 4 currently only supports the active directory domain controller server role. For now, we'll force Samba config into DC server role, but provide a fragment for expansion later. There is a long explaintion behind this, but for now, restriction doesn't hurt us. SME as a DC will provide auth for both domain membership and simple shares by either joining the domain or logging into the server every time.
Configuration Database Parameters to Modify
SMBD : Delete
NMBD : Delete
SMB : In general, all of the template fragments have been redesigned to allow dbase parameters to override many Samba defaults. Specific parameters that need to be defined or modified are as follows:
- ServerRole: Redefine with the following:
- SA: Stand Alone Server Mode
- BD: Backup Domain Controller/Member
- DC: Domain Controller (Current default. See server role explanation)
- UnixCharSet: Delete
- KernelOplocks: Add and set to enabled
- Level2Oplocks: Add and set to enabled
- OSLevel: Redefine to 65
- dnsForwarder: New parameter that could be defined to forward DNS requests from the Samba DNS to another DNS.
Services to Modify
smbd : Remove nmbd : Remove samba: Create new daemontools service using smbd as a template
