Description

Our current testcase does not support opensuse linux.

Solution

We want to adapt the test in a way, that supports these linux flavors.

Alternatives

No response

Additional information

Currently the tests fail on a PAM task. (https://github.com/dev-sec/ansible-collection-hardening/actions/runs/4664154812/jobs/8256308779)

It seems that opensuse has it's config files in different locations. I could identify some alternative paths, but this needs verification

• ssh config is in /usr/etc/ssh/
• PAM files are in /usr/lib/pam.d/
