Ubuntu 1. 4. 0. 4 Active Directory Authentication. In a post a couple of years ago I gave an example on how to configure an Ubuntu 1. HelloWe are trying to obtain access to a remote MS SQL Server database from our SAP Netweaver 7. EHP 2 in our develop environment. Our platform is with Oracle 11.

Installation Samba Aix' title='Installation Samba Aix' />Active Directory. Things used to be hard back then. Installation Samba Aix RoseNow we have the realmd realm enrollment manager to do the hard work of joining the host to an Active Directory domain, and the System Security Services Daemon or SSSD to do the actual authentication and authorization work whenever it is needed. And things are much easier to configure and get running. Also in the mean time Microsoft has deprecated the Identity Management for UNIX extension to Active Directory. It used to be used to manage POSIX attributes in the AD for use by UNIX clients. Luckily, the SSSD has a nice coherent way of mapping Windows user and group ids to UNIX ones so that POSIX attributes may not be needed at all in the AD anymore, making things more straighforward. If you still need to be able configure attributes by individual LDAP entry basis, you may need to look into Free. IPA and ID Views. The automatic id mapping is not compatible with the old POSIX attributes in the sense that once you enable automatic id mapping, all the existing POSIX attributes are ignored. So you may have to fix group memberships, for example, if your POSIX group memberships dont match the Windows group memberships the Windows group memberships are the ones that will be used with id mapping. And of course all the uid numbers will be changed when you flip the switch and enable automatic id mapping. If you havent been using POSIX attributes in the AD schema before, you dont have to worry about anything I said in the last paragraph.

SSSD and realmd can be found in the Ubuntu repositories, so installation is easy. But a couple of things must be taken care of first. The first prerequisite is, make sure you are using your Active Directory DNS servers. They will be used to query the addresses of the domain controllers, and when the domain is joined, DNS records forward and reverse are added. The second prerequisite is that your time keeping should closely match the AD domain controller machines usually within 5 minutes of each other. Use your domain controllers as NTP time sources, or at least use the same time sources for the domain controllers and the Linux hosts to keep their clocks very close to each other. Install Kerberos client, SSSD and tools. Install the Kerberos client, the realm enrollment tool, the System Security Services Daemon, the AD client tool, and Samba tools. When prompted, type in your AD Kerberos realm. It should generally be your domain name in capital letters koo. KOO. FI. If your DNS is working properly, that should be all that is needed for the Kerberos client to work alright. Otherwise you may need to add your servers to etckrb. Authenticating with Kerberos. Try getting a Kerberos ticket as domain administrator. KOO. FI. klistkinit administratorKOO. FIklist. The output of klist should look like this. Ticket cache FILE tmpkrb. Default principal administratorKOO. FI. Valid starting Expires Service principal. KOO. FIKOO. FI. renew until 0. Ticket cache FILE tmpkrb. Defaultprincipal administratorKOO. FIValid starting     Expires            Service principal. KOO. FIKOO. FIrenew until. That shows we now have a ticket valid for some hours, meaning the Kerberos authentication is working fine to the domain controller. We can proceed to configuring the realmd realm enrollment tool which will join us to the domain, and later use this ticket to actually execute the join operation. Configuring realmd. Edit etcrealmd.

The automatic installno option will disable automatic installation of packages by realmd. The default homehomeDU option will make the home directories of users be of form homeDOMAINUSERNAME, eg. The default shell is the shell for users. The computer ou option tells where the machine account will be added in AD. The automatic id mappingyes option makes SSSD use automatic id mapping instead of user and group ids stored in POSIX attributes in AD. The SSSD automatic id mapping is intelligent in that it can guarantee the same UNIX uid and gid on different hosts when all the hosts are using SSSD. The fully qualified namesno option will by default remove the domain part from user and group names. It may result in name collisions, but makes things easier for users since they only have to type in their username part and not the domain part every time. Joining The Host to the Active Directory Domain. You can use the realm discover command to see if the Active Directory domain can be discovered. It requires avalid Kerberos ticket as a domain administrator. Output should look like. KOO. FI. domain name koo. KOO. FI  domain name koo. We have all the required packages already installed, so lets just join. Output looks like. KOO. FI. domain name koo. U. login policy allow realm loginskoo. KOO. FI  domain name koo. U  login policy allow realm logins. After a successful join, you should be able to resolve individual users and groups using getent. Domain Admins. domain admins 3. Domain Admins domain admins 3. If you run into a Failed to join the domain error, try the join with user given as an option. If you run into a Necessary packages are not installed error, you may try to install packagekit. And then try again. Theres a bug in Launchpad about it. Controlling Who Can Log In. Also at this point you should be able to log in with any AD user id by default. You can control who can and who cannot login with. Domain Adminsrealm deny allrealm permit administratorrealm permit gDomain AdminsYou can see the changed policy and permitted logins with.

For performance reasons by default SSSD will not try to enumerate every user and group from AD, but will only query for them when requested. If you want to enable enumeration, add. Trueunder your domain stanza in sssd. It is quick for a small directory, but may be slow for a large one. It can be handy for debugging, as you can list all users and groups withgetent passwd and getent group. Automatic Home Directories. To create home directories at first login, add a pammkhomedir. Thats basicly it. At this point you should have a fully functioning AD login for selected users on your Ubuntu server. Internals. The machine account Kerberos principal is saved into the file etckrb.
