Roadmap

Revision as of 22:23, 5 September 2013 by Abartlet (talk | contribs) (change how we express the OpenLDAP backend)

Introduction

This page describes the bigger next steps in the development of Samba. It is not named roadmap since it does presently not provide a timeline. The purpose is to point out the broader direction into which Samba is heading.

Active Directory Server

Trust support

A lot of DCE/RPC work needs to be done before we can really finish this task.

  • async schannel (NETLOGON) client (Metze)
  • merged crypto handling for samlogon cred validation (Günther/Metze)
  • merged libnetjoin interfaces (Günther/Metze)
  • DCE/RPC client API changes (Günther/Metze)
    • tevent based async infrastructure (new services: witness, replication, snapshot, PAR)
    • client context (get rid of lp_ usage and globals for client details)
    • association group implementation
  • DCE/RPC server API merge and cleanup

Some of the existing work can be found already here:

Abstract data model

We might want to implement the abstract data model as outlined in MS-ADPS and other specs. This would allow to abstract the existing interfaces (dsdb/passdb) which both are not the best match for trust handling. Once we have that, and we have the common DCE/RPC infrastructure, we can easily plug implementations for trusts (e.g. from s3) into s4 (and vice-versa).

Testing

  • We need to find a way to setup multi-trust environments during make test to test more compelx scenarios (e.g. the forst trust test from Sumit Bose).
  • We need to test trust calls on MEMBER and DC configurations.

LSA/Netlogon

  • Samba4 lacks support for some LSA and Netlogon calls related to trusts, some of them exist in s3 some are in my master-netlogon branch.

File Server (smbd)

SMB2

  • SMB2 leases

SMB3

  • multi-channel
  • persistent file handles
  • witness notification protocol
    • asynchronous RPC server
  • RDMA (SMB direct)
  • directory leases
  • clustering
    • continuously available shares, scale-out shares

CTDB

  • integrate CTDB master into samba master
