Simple basic auth ( replace of #85 )

[sawanoboly]

replace of #85

Add BasicAuth to chef-zero.

If given option `-auth-string STRING` or initialize ChefZero::Server with `:auth_string`  `server = ChefZero::Server.new(:auth_string => 'foobar')`, then chef_server_url will be provided as `'http://foobar@localhost:8889'`

UseCase:

1. We run chef-client local-mode on a shared-hosting server with recipe which spends long time.
2. The server listens local port during chef-client running.
3. Maybe, shared-hosting users could retrieve my cookbooks or other resources via http://localhost:8889.

Hmm. The right thing to do here might be to just add authentication. (It turns out it's not hard.)

[sawanoboly]

I feel that the chefzero doesn't need supporting real authentication like the chef-server.
Because of managing client pubkeys, expiring sessions... It is a troublesome.

Whatever you want to do.

[jkeiser]

It already manages client keys, so I don't think that's much of an issue :) And there is no session concept or expiration.

Only reason I'd prefer that is I'd rather not introduce two authentication concepts (basic and chef) over time.

[sawanoboly]

I see. Please close it.

Can I use authentication feature with v3.0?

[jkeiser]

If it's all right, I'd like to leave this open to remind me. 3.0 doesn't have authentication yet.

Out of curiosity, will unix domain sockets work for you? You can start chef-zero on a unix socket and it will communicate over that. Those can be secured, so you should be able to keep communications silent as long as people are not using the same unix user ...

[sawanoboly]

Thanks, to use the domain socket sounds good.
But I would like use the chefzero via HTTP over SSH port-forwarding with knife-plugin which I wrote.
So, I am glad if to be able to authenticate.

FYI, the plugin is knfe-zero.

Hi,
since local-mode is now in process by default, and we'd rather not have chef-zero support different authentication modes to chef-server, we're going to close this Pull Request. Thanks for your contribution.
