Passwordless SSH setup instructions in the configuration guide are not clear for Mac

[mayur-raja]

Describe the bug
The Passwordless SSH setup instructions in the configuration_guide.md file are for Linux and not Mac OS X. The instructions for Mac OS X are very different. There is an excellent guide here:

https://help.dreamhost.com/hc/en-us/articles/216499537-How-to-configure-passwordless-login-in-Mac-OS-X-and-Linux

I just pointed to my z/OS host server and used my custom public key file and managed to configure passwordless ssh signon to my z/OS host server.

Also note that these instructions clearly tell you whether a command is to be entered on the local client (Mac) or on the server (z/OS). Another good thing is that additional instructions are included to allow you to verify things as you proceed. You have to remember that this is not something that people do everyday so it is good to have such additional commands.

To Reproduce
Try issuing the currently stated commands on Mac OS X and see if they work or not. You will find that they do not work.

Expected behaviour

ssh user@mvshost.com (for example) should connect to the host without having to specify the password but it does not work.

Thank you for taking the time to comment on your experience with SSH Keys. Password-less SSH is pretty commonly documented throughout the internet, I agree this is a nice guide, we typically won't point to non enterprise content as docs such as this could be short lived. That said, ssh-copy-id is available for Mac, it was intended to be a generic high level explanation, I will add more specific notes to aid in this topic. If @RadhaV2020 would like to take this further and dedicate a section to this topic, I will discuss this with her. This is what I have started and will add more.

@RadhaV2020 - maybe content from our Ansible development docs need to be brought into the playbook repository, referring to https://ibm.github.io/z_ansible_collections_doc/ibm_zos_ims/docs/source/community_guides_docs/zos_ansible_module_testing.html?highlight=keygen#ssh-keys
