Jeff Mitchell 4f0310ed96 Don't allow root from authentication backends either.
We've disabled this in the token store, but it makes no sense to have
that disabled but have it enabled elsewhere. It's the same issue across
all, so simply remove the ability altogether.

The GitHub auth backend allows authentication with Vault using GitHub.

# Auth Backend: GitHub
Name: `github`
The GitHub auth backend can be used to authenticate with Vault using
a GitHub personal access token.
This method of authentication is most useful for humans: operators or
developers using Vault directly via the CLI.
## Authentication
#### Via the CLI
```
$ vault auth -method=github token=<api token>
...
```
#### Via the API
The endpoint for the GitHub login is `auth/github/login`.
The `github` mountpoint value in the url is the default mountpoint value.
If you have mounted the `github` backend with a different mountpoint, use that value.
The `token` should be sent in the POST body encoded as JSON.
```shell
$ curl $VAULT_ADDR/v1/auth/github/login \
-d '{ "token": "your_github_personal_access_token" }'
```
The response will be in JSON. For example:
```javascript
{
"lease_id": "",
"renewable": false,
"lease_duration": 0,
"data": null,
"warnings": null,
"auth": {
"client_token": "c4f280f6-fdb2-18eb-89d3-589e2e834cdb",
"policies": [
"admins"
],
"metadata": {
"org": "test_org",
"username": "rajanadar",
},
"lease_duration": 0,
"renewable": false
}
}
```
## Configuration
First, you must enable the GitHub auth backend:
```
$ vault auth-enable github
Successfully enabled 'github' at 'github'!
```
Now when you run `vault auth -methods`, the GitHub backend is available:
```
Path Type Description
github/ github
token/ token token based credentials
```
Prior to using the GitHub auth backend, it must be configured. To
configure it, use the `/config` endpoint with the following arguments:
* `organization` (string, required) - The organization name a user must
be a part of to authenticate.
* `base_url` (string, optional) - For GitHub Enterprise or other API-compatible
servers, the base URL to access the server.
* `max_ttl` (string, optional) - Maximum duration after which authentication will be expired.
This must be a string in a format parsable by Go's [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)
* `ttl` (string, optional) - Duration after which authentication will be expired.
This must be a string in a format parsable by Go's [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)
###Generate a GitHub Personal Access Token
Access your Personal Access Tokens in GitHub at [https://github.com/settings/tokens](https://github.com/settings/tokens).
Generate a new Token that has the scope `read:org`. Save the generated token. This is what you will provide to vault.
For example:
```
$ vault write auth/github/config organization=hashicorp
Success! Data written to: auth/github/config
```
After configuring that, you must map the teams of that organization to
policies within Vault. Use the `map/teams/<team>` endpoints to do that.
Team names must be slugified, so if your team name is: `Some Amazing Team`,
you will need to include it as: `some-amazing-team`.
Example:
```
$ vault write auth/github/map/teams/admins value=admins
Success! Data written to: auth/github/map/teams/admins
```
The above would make anyone in the "admins" team receive tokens with the policy `admins`.
You can then auth with a user that is a member of the "admins" team using a Personal Access Token with the `read:org` scope.
GitHub token can also be supplied from the env variable `VAULT_AUTH_GITHUB_TOKEN`.
```
$ vault auth -method=github token=000000905b381e723b3d6a7d52f148a5d43c4b45
Successfully authenticated! The policies that are associated
with this token are listed below:
admins
```
