QA:Testcase FreeIPA realmd login

Description

Check that FreeIPA's HBAC rules are respected after using realmd to join the current machine to a FreeIPA domain.

Setup

1. Run through the test case to join the domain.

How to test

1. The intent here is to set up an HBAC rule which specifies that all access is prohibited, unless it is initiated by a specific user ("testuser")
2. Create a FreeIPA user (after acquiring admin credentials)

   $ kinit admin

   $ ipa user-add testuser --first test --last user --password

3. Create an HBAC rule that allows access to the user you just created

   $ ipa hbacrule-add testrule --servicecat=all --hostcat=all

   $ ipa hbacrule-add-user testrule --users=testuser

4. Disable the default rule that allows access to everyone

   $ ipa hbacrule-disable allow_all

Expected Results

1. Make sure that admin is not able to ssh into the IPA server (per the HBAC rule)

   $ ssh admin@server.example.org

2. Make sure that testuser is able to ssh into the IPA server (per the HBAC rule)

   $ ssh testuser@sever.example.org

Clean-up after the test

Enable the allow_all rule again to avoid interference with other Test cases:

$ ipa hbacrule-enable allow_all

Troubleshooting

The selinux profile for realmd isn't yet stable, so you may want turn off enforcement. Please do still file bugs for the SElinux AVC notifications you see.

Known Issue [Selinux]: You need to turn off selinux to complete the join. Please do:

$ sudo setenforce 0

Please file all realmd AVC's at this bug: https://bugzilla.redhat.com/show_bug.cgi?id=867873

$ sudo grep realmd /var/log/audit/audit.log
