home directory: it’s by default For example, the AD user john will have a home directory of use_fully_qualified_names: users will be of the form not just user.

cache_credentials: this allows logins when the AD server is unreachable.

Let’s highlight a few things from this config: Something very important to remember is that this file must have permissions 0600 and ownership root:root, or else sssd won’t start! Realmd_tags = manages-system joined-with-adcli The realm tool already took care of creating an sssd configuration, adding the pam and nss modules, and starting the necessary services. For that, use the -one-time-password option. If you need to use another account, pass it to the tool with the -U option.Īnother popular way of joining a domain is using an OTP, or One Time Password, token. * Added the entries to the keytab: FILE:/etc/krb5.keytabīy default, realm will use the Administrator account of the domain to request the join. * Retrieved kvno '3' for computer account in directory: CN=AD-CLIENT,CN=Computers,DC=ad1,DC=example,DC=com * Found computer account for AD-CLIENT$ at: CN=AD-CLIENT,CN=Computers,DC=ad1,DC=example,DC=com

* Generated 120 character computer password * Authenticated as user: Looked up short domain name: AD1 * Wrote out nf snippet to /var/cache/realmd/adcli-krb5-hUfTUg/krb5.d/adcli-krb5-conf-hv2kzi * Sending NetLogon ping to domain controller: 10.51.0.5 * Calculated computer account name from fqdn: AD-CLIENT * LANG=C /usr/sbin/adcli join -verbose -domain -domain-realm -domain-controller 10.51.0.5 -login-type user -login-user Administrator -stdin-password If you want to see what it was doing, pass the -v option: $ sudo realm join -v Now let’s join the domain: $ sudo realm join

sssd can install the missing packages via packagekit, but we installed them already previously.

This performs several checks and determines the best software stack to use with sssd. * Performing LDAP DSE lookup on: 10.51.0.5 Let’s verify the domain is discoverable via DNS: $ sudo realm -v discover We will use the realm command, from the realmd package, to join the domain and create the sssd configuration. Install the following packages: sudo apt install sssd-ad sssd-tools realmd adcli System time is correct and in sync, maintained via a service like chrony or ntp The domain controller is the primary DNS resolver (check with systemd-resolve -status) The domain controller is acting as an authoritative DNS server for the domain. This guide assumes that a working Active Directory domain is already configured and you have access to the credentials to join a machine to that domain.

This guide does not explain Active Directory, how it works, how to set one up, or how to maintain it. Prerequisites, Assumptions, and Requirements Group membership will also be maintained. At the end, Active Directory users will be able to login on the host using their AD credentials.

This section describes the use of sssd to authenticate user logins against an Active Directory via using sssd’s “ad” provider. This guide will focus on the most common scenarios where SSSD is deployed. To allow for disconnected operation, SSSD also can also cache this information, so that users can continue to login in the event of a network failure, or other problem of the same sort. SSSD provides PAM and NSS modules to integrate these remote sources into your system and allow remote users to login and be recognized as valid users, including group membership. SSSD stands for System Security Services Daemon and it’s actually a collection of daemons that handle authentication, authorization, and user and group information from a variety of network sources.
