Introduction This post describes all the millions of configuration files you need to set up on a CLIENT LINUX server / machine in order to ssh to it with your domain credentials. I have this working in a LAB environment with the following caveats: SELINUX disabled (work on this required) Firewall Disabled (not hard to fix this if required) DNS Setup not working completely for Forwarding to external Nameserver by Samba4.  Don't know why. (more investigation required) You will need to have a user called binduser which has permissions in AD to look up other users.  I am sure there is documentation on this around somewhere :) Install packages yum -y install samba-winbind pam_ldap pam_krb5 nss-pam-ldapd oddjob-mkhomedir bind-utils Configure openldap (/etc/openldap/ldap.conf) [root@linuxclient ~]# cat /etc/openldap/ldap.conf # # LDAP Defaults # # See ldap.conf(5) for details # This file should be world readable but not world writable. #BASE dc=example,dc=...

Importing LDIF files into Samba4 and Active Directory This is part 2 of the Extending AD Schema on Samba4 series.  The examples below are tested using the Samba4 LAB I created.  If you want more information on how that works then please read  http://david-latham.blogspot.co.nz/2012/12/samba4-ga-release-virtualbox-lab.html For part one, please read http://david-latham.blogspot.co.nz/2012/12/extending-ad-schema-on-samba4.html Unfortunately the format of an ldif file for creating new attributes and classes in the Schema Configuration are differ between Samba4 and Microsoft. The tools are slightly different too.  So this article will attempt to make it all clear. Find all the latest versions of code on this post at  https://github.com/linuxplayground/yubikey-ldap/tree/master/microsoft-schema Samba4 - ldbadd & ldbmodify As far as I can tell the only way to create a new class with a custom attribute in Samba4 (on the Linux command line) is first add ...

My last post on Samba4 showed how easy it is to install and configure an AD Service on Linux.  If you've not read it then please have a look. ( http://david-latham.blogspot.co.nz/2012/12/samba4-ga-release-virtualbox-lab.html ) This post show's how to extend the Samba4 Active Directory Schema.  Specifically for YubiKey integration. YubiKey's can be purchased for a relativlely low price from Yubico.  Please visit their website (www.yubico.com) for more information. LDAP Integration is very well covered by Michal Ludvig on his website and github.  ( http://www.logix.cz/michal/devel/yubikey-ldap/ ) In fact we are planning to leverage his implementation at our work and are considering donating towards what's obviously a very good cause. Now seeing as though LDAP and AD are so similar and exhibit many of the same APIs, I began to wonder how this might fit in with Samba4.  Eventually we might end up using Samba4 for our domain and so I needed to figure out if ...
