Description

Leave an active directory domain by removing the computer account, and then deconfiguring locally.

Setup

  1. Make sure you have other required software:
    • realmd 0.14.0 or later
  2. Verify that your Active Directory domain access works, or set a domain up.
  3. Run through the test case to join the domain.
  4. Verify that you are joined to the domain with the following command 
    $ realm list
    Make sure you have a configured: kerberos-membership line in the output.
    Note the login-formats: line.
  5. Check that you can resolve domain accounts on the local computer.
    Use the login-formats you saw above, to build a remote user name. It will be in the form of DOMAIN\User, where DOMAIN is the first part of your full Active Directory domain name.
    $ getent passwd 'AD\User'

How to test

  1. Perform the leave command. 
    $ realm leave --remove --user=User ad.example.com
    You will be prompted for Policy Kit authorization, because you're not running as root.
    You will be prompted for a password.
    This can take a minute or two depending on how far away you are from the directory.
    On a successful leave there will be no output.

Expected Results

  1. Check that the domain is no longer configured. 
    $ realm list
    Make sure the domain is not listed.
  2. Check that you cannot resolve domain accounts on the local computer. 
    $ getent passwd 'AD\User'
    There should be no output.
  3. Check that there is no machine account for the domain in the keytab. 
    sudo klist -k
    You should see no lines referring to the domain in the table, or an error message saying that the keytab does not exist.
  4. If you have console access to a domain controller, you can use the Active Directory Users and Computers tool to see if that the computer account was deleted.



Troubleshooting

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

$ realm leave --remove --user=User --verbose ad.example.com
