While we're testing SSH, it seems that we skipped one important part, particularly for stagings, which led to bsc#1217220 not being catched by our testing.

All in all, we should enable two different tests:
1- password login
2- ssh-key login

Acceptance Criteria¶

1. New test scenario called Authentication Stack is created
2. Testsuite is enabled in All of osd stagings.
3. Testsuite is enabled for maintenance incidents.
4. Testsuite is enabled for maintenance incidents.
5. PR is created to enable this test for Microos and Leap Micro (request review from Dimstar before enabling)

Order of importance¶

1. Microos
2. ALP
3. Leap
4. SLE

Notes¶

1. It is important NOT to modify /etc/ssh/sshd_config but rather to apply the changes on its own file i.e /etc/ssh/sshd_config.d/99-bsc1217220.conf to ensure loading of config files is not broken or disabled without knowing.
2. The test should be local only (i.e ssh root@localhost)

The test doesn't really need to do much, other than the login with password and with ssh key, I see that we do or have tests for this in quite few places, but we also have tests/console/sshd.pm which doesn't seeem to cover this case, however it would be great to either adapt it, or come up with a test module that is self contained, and aware of transactional systems
