Description
Leave an active directory domain by deconfiguring it locally.
Setup
- Verify that your Active Directory domain access works. If you don't have an Active Directory domain, you can set one up.
- Run through the test case to join the domain.
- Verify that you are joined to the domain with the following command
$ realm list
- Make sure you have a
configured: kerberos-membershipline in the output. - Note the
login-formats:line.
- Check that you can resolve domain accounts on the local computer.
- Use the
login-formatsyou saw above, to build a remote user name. It will be in the form ofDOMAIN\User, where DOMAIN is the first part of your full Active Directory domain name. $ getent passwd 'AD\User'
- Use the
How to test
- Perform the leave command.
$ realm leave ad.example.com
- You will be prompted for Policy Kit authorization.
- You will not be prompted for a password.
- This should proceed quickly, not take more that 10 seconds.
- On a successful leave there will be no output.
Expected Results
- Check that the domain is no longer configured.
$ realm list
- Make sure the domain is not listed.
- Check that you cannot resolve domain accounts on the local computer.
$ getent passwd 'AD\User'
- There should be no output.
- Use the
login-formatsyou saw above, to build a remote user name. It will be in the form ofDOMAIN\User, where DOMAIN is the first part of your full Active Directory domain name.
- 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.
- 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 not 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 --verbose ad.example.com
