QA:Testcase realmd join packages

Description

Join the current machine to an Active Directory, and prevent automatic installation of packages.

Setup

1. Fulfill the prerequisites and make sure your Active Directory domain access works. realmd 0.14.0+ and adcli 0.6+ are required.
2. You need a domain account as an administrator.
3. Leave realm(s) you are currently joined to.
4. Remove necessary packages for joining active directory:

   $ sudo yum remove sssd adcli sssd-tools

5. Tell realmd not to automatically install packages, by placing these lines in your /etc/realmd.conf.

[service]
automatic-install = no

Make sure realmd is restarted:

$ sudo killall realmd

How to test

1. Discover the domain, which should list the required packages:

   $ realm discover ad.example.com

   Check the required-package lines.

2. Try to join the domain, which should fail and list packages needed:

   $ realm join --user=Administrator server.ad.example.com

   The packages needed should be listed, like: sssd, sssd-tools

Expected Results

1. Now install the packages listed above using a yum command:

   $ sudo yum install sssd adcli sssd-tools samba-common

2. Perform the join again, this time it should complete without error

Troubleshooting

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

$ realm join --verbose server.ad.example.com
