Hi KyleJamesWalker! You've successfully authenticated, but GitHub does not provide shell access.

This no longer seems to be working on 1.5.

I also had to change my hosts-vagrant file from:

[vagrant]
192.168.123.10

[local]
127.0.0.1

to:

[vagrant]
default         ansible_ssh_host=192.168.123.10

[local]
127.0.0.1       ansible_connection=local

but my local ansible section is still being passed over.

local_action works though.
