Description

This test case ensures that you can enrol a machine as a client in an Active Directory or FreeIPA domain with the realm command, using sssd as an AD or FreeIPA client.

Setup

1. Deploy a correctly-configured FreeIPA or Active Directory domain controller. You can follow:

   QA:Testcase_Server_role_deploy with the Domain Controller role to deploy a FreeIPA domain controller on Fedora 28 or earlier

   QA:Testcase_freeipa_trust_server_installation to deploy a FreeIPA domain controller on Fedora 29 or later

   QA:Testcase_Active_Directory_Setup to deploy an Active Directory domain controller

2. Create at least one domain account, either a user or administrator. It's useful to test with both
3. Ensure the test client has a fully-qualified hostname (e.g. client.example.com). Do not proceed if running hostname returns localhost or similar
4. Ensure the realmd package is installed on the test client (e.g. su -c 'dnf install realmd')
5. Remove the sssd, freeipa-client and samba-client packages (e.g. su -c 'dnf remove sssd samba-client') from the test client, they should be installed by realmd if necessary
6. Unless you wish to test pending updates, disable the 'updates-testing' repository so realmd does not install packages from it: su -c 'dnf config-manager --set-disabled updates-testing'
7. Install the krb5-workstation package to get the 'klist' and 'kinit' tools.
8. The client must be capable of resolving the FreeIPA or Active Directory servers by FQDN. The easiest method of accomplishing this is to use Cockpit to modify the default DNS server address to be the IP address of the domain controller. If the domain controller is not running a DNS server, the alternative is to modify /etc/hosts on the client to contain the appropriate IP address for the domain controller FQDN.

How to test

1. Perform the join command. Use the --user=xxx argument to specify your domain account name, and replace dc.example.com with the fully-qualified hostname of the domain controller

   realm join --user=(username) dc.example.com

   You will be prompted for a password for the account

   You will be prompted for PolicyKit authorization, because you are not running the command as root

   On a successful join there will be no output

   This can take up to a few minutes depending on how far away your domain controller is.

Expected Results

1. Check that the domain is now configured: realm list

   Make sure the domain is listed

   Make sure you have a configured: kerberos-member line in the output

2. Check that you can resolve domain accounts on the local computer

   For Active Directory:

   getent passwd 'DOMAIN\User' (DOMAIN is the netbios name, usually the first portion of the domain name, e.g. AD or SAMDOM; make sure to use the single quotes)

   For FreeIPA:

   getent passwd admin@domain (domain is the fully-qualified FreeIPA domain name, e.g. example.ipa)

   You should see an output line that looks like passwd output. It should contain an appropriate home directory, and a shell

3. Check that you have an appropriate entry in your host's keytab: su -c 'klist -k'

   You should see several lines with your host name. For example 1 host/$hostname$@FQDN

4. Check that you can use your keytab with kerberos: su -c 'kinit -k (principal)'

   Replace (principal) with the principal from the output of the klist command above. Use the one with the domain capitalized and that looks like host/hostname@DOMAIN) (FreeIPA) or TRUNCATED_HOSTNAME$@DOMAIN (Active Directory)

   There should be no output from this command

5. If you are testing FreeIPA and have set up the FreeIPA Web UI, you can use it to see that the computer account was created under the Hosts section
6. If you have are testing Active Directory and have console access to the domain controller, you can use the Active Directory Users and Computers tool to see if that the computer account was created under the Computers section
7. Optionally, move on to QA:Testcase_domain_client_authenticate to ensure you can log in with a domain account.

Troubleshooting

Use the --verbose argument to see details of what's being done during a join. Include verbose output in any bug reports.
