• [Samba] Best way to integrate Unix with AD.

    From A. James Lewis via samba@21:1/5 to All on Mon Mar 13 21:40:02 2017
    Hi all,

    I know this is a little off topic (although it might not be because I'm sure there's a solution involving Samba!)... but I hope one of you fine people can advise me on the best approach to achieving an integrated directory supporting Unix/Linux as a
    first class citizen, storing autofs maps, as well as uid, gid and home folders for each user... and how would that be managed.

    I see Microsoft is removing the Unix services extensions with Server 2016, so I'm really wondering what the best, and most long term sustainable way to integrate a directory so that both platforms operate as intended, and those users are manageable.

    From my understanding, they only removed the idmu server etc, they
    haven't removed the RFC2307 attributes. Even if they did, Samba would
    still have them.

    You can use samba-tool to manage the creation of RFC2307 users and
    groups.

    also offers some clarification around this.

    Is there a good guide for how to set up a Samba based AD domain
    controller with RFC2307 attributes so I can experiment... I can't get
    the Windows guys in my company to do anything Microsoft don't provide a
    check box for, unless I can teach them how to do it... but I've not used
    any of these Windows technologies for a very long time...

    At least if I can show a working system then someone from the Windows
    team might consider looking at it.... and if I tell them to do
    something that ultimately doesn't work, we'll be back to square one but
    they will be doubly reluctant, so I need to learn more about AD than
    them... sigh.

    I saw a talk about this sort of integration at a conference earlier
    this month, descriptions/slides:

    They streamed it to youtube but unfortunately the audio quality is poor:

    I am trying to setup Windows 2012R2 as the directory server . this is to migrate from a classic domain with Oracle ldap server backend for samba
    data, unix accounts, autofs etc. Samba 4 as an AD domain does not
    fully support trusts, and I don't feel comfortable using Samba as a
    directory server in a domain or forest that will have exchange
    servers. And if I am going thru migration pain I might as well just
    switch to Windows domain servers. I haven't worked with Windows 2016
    yet.


    If I can get RFC2307bis schema added to the AD schema then that should
    take care of the major hurdle to implementing autofs support. With
    linux, autofs configuration is flexible to support the "old" RFC2307
    autofs syntax. However, solaris expects the newer RFC2307bis syntax.
    If you don't have solaris then you can probably manage with the older
    syntax.


    I also have been looking at Centrify's web site- I don't think they
    provide a meta-directory, but instead they provide linux AD client
    software. This might make some of the administration and deployment simpler. I don't think it is essential.
