What's it good for?Samba 4 is just a version of Samba that is newer than Samba 3. Samba 4 can be a file server, an NT4 PDC, an active directory domain controller, or an NT4 or AD member server. Probably other things I am forgetting too. "Single Sign On" is a term used by many people to mean different things. To some people, it means you can use the same password to log into any system. To some, it means into any resource. To other, it means that once you log into a system, you have passwordless login into any other resource. All of these things are possible (within limitations) with samba.> As to what *I* require, scenario: I am sitting at a linux workstation on our > office network, any linux workstation, not just the one in *my* office.

You basically just need to follow the directions here: https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server> I will investigate the recommendations posted by L.P.H. van Belle and Guilherme > Boing and see if I can make some headway.No offense against L.P.H. van Belle, but his directions are for the hard way to set up kerberos. Creating a domain controller handles all of the server side, and "net ads join" handles all of the client side if you are using winbind. If you prefer not to join your machines to the domain and use LDAP to authenticate, Guilherme's documentation looks like a good start. Also note that some distros have tools to automate some or all of the PAM/NSS stuff (this applies to the member server directions above as well), so you may want to check your distro docs too. Redhat/Fedora in particular has authconfig, and in newer versions realmd.

The first thing you need to understand is there is only one basic way to setup Samba in an AD domain, it is what you do with Samba after this that defines what it will be used for. There is a page on the Samba wiki that purports to be for a member server, well, in my opinion, it is just the basic setup and you would need to extend it to make it a proper member server, you can also use this basic setup for a workstation. Most, if not all, of the information you require is on the wiki and you only have to ask here about any gaps you find. Rowland

The "Server" bit in the link gives me pause. I *have* a Samba4 AD/DC "server" already. I think the linux workstations need to be "clients", but maybe this is just a matter of semantics. I'll research.> If you prefer not to join your machines to the domain and use LDAP to > authenticate, Guilherme's documentation looks like a good start.I prefer the simplest approach. If there is some way I can get this to work without adding LDAP, PAM, kerberos, NSS, etc. I'm all for it. Note that in my Windows example the workstation is joined to the domain. That's fine I have no problem with that versus not joining. I'm looking for the easiest, simplest way for workstation users to log into any (linux) workstation in the LAN with ONE SET of credentials. So far I haven't found this "magic bullet" after months of surfing.> you may want to check your distro docs tooI'm using Ubuntu as the client workstations. Apparently, Ubuntu knowns nothing about Samba4 AD/DC and the docs have lots of instruction on setting up OpenLDAP, Kerberos, etc. Things that aren't going to work (at least on the server side) with Samba4 since it has its own built-in versions of these things. --Mark -----Original Message-----> Date: Thu, 8 Oct 2015 15:46:50 -0500 (CDT) > From: Sketch <smblist at rednsx.org> > To: Mark Foley <mfoley at ohprs.org> > cc: samba at lists.samba.org > Subject: Re: [Samba] Samba AD PDC , LDAP and Single-Sign-On > > On Thu, 8 Oct 2015, Mark Foley wrote: > > > On Oct 8 2015 09:32 Rowlan Penny wrote: > > > >> It might help if you were to explain just what you require from single-sign-on ? > > > > Well, perhaps I'm mistaken, but is this not the #1 reason to install Samba4? > > From reading this list over the past couple of months it does not seem that > > Authenticating users on Windows workstations is the main thing people do.

I've been messing around with GPOs on Windows AD domains for years, more extensively this past year with Samba4 AD/DC and I absolutely hate them. In my opinion they are yet another attempt by Microsoft to shore up a fundamentally insecure OS. I have yet to find a GPO that would be worthwhile in Linux. "Trust Center"? Gee, can't execute macros in Linux that run as root - don't need that. "Remote Desktop GPO"? How about VNC. I've got more, lots more, but I'll stop. If you can give me an example of one GPO that would be useful in Linux I'll moderate my position. Sorry to get on a rant, but if we do manage to convert away from Windows, I say "good riddance" to GPOs!> There is a page on the Samba wiki that purports to be for a member > server, well, in my opinion, it is just the basic setup and you would > need to extend it to make it a proper member server, you can also use > this basic setup for a workstation. > > Most, if not all, of the information you require is on the wiki and you > only have to ask here about any gaps you find.That's great!!! I've been searching for that particular wiki for a couple of months now without success. Can you point me to it?
