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. For example, cached credentials should be disabled on all your servers and probably all your desktop computers also - only mobile users really need them so they can log onto their laptops when they're away from the office.Multi-node Configuration with Docker-Compose And second, you can use Group Policy to disable credential caching on machines that don't need it. First, use Group Policy to force users to use strong passwords as this will make trying to crack cached credentials unfeasible due to the length of time needed to crack them. If you're still worried however concerning the security of cached credentials, you can do two things to mitigate the risks.

And finally, to crack cached credentials an attacker would need to run a password cracker under the LocalSystem account, in which case they have complete control of your machine anyway so you've got more important things to worry about, right? Instead, it stores them as the hash of a hash, salted with your username, and this makes them very difficult to crack using a password cracker. Second, cached credentials doesn't actually store your credentials (username and password) or even the NT hash of your credentials. First, cached credentials are stored in the Security hive and not in LSA Secrets (a much less secure place for storing credentials). Steve and Jesper make the following points concerning how Windows implements caching of domain credentials.

But how serious a vulnerability is this? To find the answer, I cracked open one of my all-time favorite books, Protect Your Windows Network: From Perimeter To Data by Jesper M. The reader told me that he heard from "some security experts" that storing domain credentials locally on client machines like this poses a security vulnerability since anyone who can gain access to your computer can run a password cracker against these stored credentials and extract your domain username and password from them.
