Permit a any domain account to log in locally, and then test that login.


  1. Make sure you have other required software:
    • realmd 0.14.0 or later
    • adcli 0.7 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 cannot 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 permit command.
    $ realm permit --all
    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 permit there will be no output.
  2. Look at the login policy:
    $ realm list
    You should see login-policy: allow-realm-login.
  3. Go to GDM by logging out, or by Switch User from the user menu.
    On a Live CD if you get automatically logged in again, go to User Accounts and turn off Auto Login for the live cd user.
  4. Choose the Not Listed? option.
  5. Type DOMAIN\User in the box.
    The case of the domain and user should not matter, but they are separated by a backslash.
    The domain part is the part of your Active Directory domain prior to the first dot.
  6. Type the user domain password, and press enter.

Expected Results

  1. You should be logged into the Fedora desktop.
  2. Open a terminal, and type:
    $ id
    Look at the output to verify that you are logged in as a domain user.


If the above explodes, try to log in from a VT console, and see if there is any interesting output there.

If you are connected to your domain controller via VPN, the above test case will not work.

You can also use pamtester, available in the Fedora software repository.

$ pamtester login 'AD\User' authenticate
