ansible requiring ansible_ssh_pass

[Graham O'Regan]

I'm running Ansible 2.1.1.0 on OS X 10.11.6 and I'm having a problem that I haven't had before. The issue the same as outlined in this SO question;

https://stackoverflow.com/questions/37213551/ansible-ssh-connection-fail

If I don't put ansible_ssh_pass in the inventory file then SSH doesn't work. I can use any value for that variable and it will be ignored in favour of the SSH cert and everything works, e.g.;

ec2-XXX-XXX-XXX-XXX.eu-west-1.compute.amazonaws.com ansible_ssh_user=ec2-user ansible_ssh_pass=dummy

The problem is that running with that inventory file on Linux fails because the password doesn't match. I've tried quite a few permutations of settings but I can't find something that works on both systems. I haven't had this issue with Ansible before using older versions.

Anyone else having the same issue?

To provide a bit more detail, if I have this in my inventory file;

ec2-XXX-XXX-XXX-XXX.eu-west-1.compute.amazonaws.com ansible_ssh_user=ec2-user ansible_ssh_pass=dummy

And run this;

$ ansible all -i inventory/aws -m ping -vvvv

No config file found; using defaults

Everything works ok, but if i set the inventory to;

ec2-XXX-XXX-XXX-XXX.eu-west-1.compute.amazonaws.com ansible_ssh_user=ec2-user

$ ansible all -i inventory/aws -m ping -vvvv

It fails :/
