I don't know if there is some version of curl that auto-generates json but the example didn't work for me on curl 7.32.0. Submitting the data as JSON works though.

# Auth Backend: Username & Password
|
|
|
|
Name: `userpass`
|
|
|
|
The "userpass" auth backend allows users to authenticate with Vault using
|
|
a username and password combination.
|
|
|
|
The username/password combinations are configured directly to the auth
|
|
backend using the `users/` path. This backend cannot read usernames and
|
|
passwords from an external source.
|
|
|
|
## Authentication
|
|
|
|
#### Via the CLI
|
|
|
|
```
|
|
$ vault auth -method=userpass \
|
|
username=foo \
|
|
password=bar
|
|
```
|
|
|
|
#### Via the API
|
|
|
|
The endpoint for the login is `auth/userpass/login/<username>`.
|
|
|
|
The password should be sent in the POST body encoded as JSON.
|
|
|
|
```shell
|
|
$ curl $VAULT_ADDR/v1/auth/userpass/login/mitchellh \
|
|
-d '{"password: "foo"}'
|
|
```
|
|
|
|
The response will be in JSON. For example:
|
|
|
|
```javascript
|
|
{
|
|
"lease_id":"",
|
|
"renewable":false,
|
|
"lease_duration":0,
|
|
"data":null,
|
|
"auth":{
|
|
"client_token":"c4f280f6-fdb2-18eb-89d3-589e2e834cdb",
|
|
"policies":[
|
|
"root"
|
|
],
|
|
"metadata":{
|
|
"username":"mitchellh"
|
|
},
|
|
"lease_duration":0,
|
|
"renewable":false
|
|
}
|
|
}
|
|
```
|
|
|
|
## Configuration
|
|
|
|
First, you must enable the username/password auth backend:
|
|
|
|
```
|
|
$ vault auth-enable userpass
|
|
Successfully enabled 'userpass' at 'userpass'!
|
|
```
|
|
|
|
Now when you run `vault auth -methods`, the username/password backend is
|
|
available:
|
|
|
|
```
|
|
Path Type Description
|
|
token/ token token based credentials
|
|
userpass/ userpass
|
|
```
|
|
|
|
To use the "userpass" auth backend, an operator must configure it with
|
|
users that are allowed to authenticate. An example is shown below.
|
|
Use `vault help` for more details.
|
|
|
|
```
|
|
$ vault write auth/userpass/users/mitchellh password=foo policies=root
|
|
...
|
|
```
|
|
|
|
The above creates a new user "mitchellh" with the password "foo" that
|
|
will be associated with the "root" policy. This is the only configuration
|
|
necessary.
