api	/sys/auth - HTTP API	docs-http-system-auth	The `/sys/auth` endpoint is used to manage auth backends in Vault.

/sys/auth

The /sys/auth endpoint is used to list, create, update, and delete auth backends. Auth backends convert user or machine-supplied information into a token which can be used for all future requests.

List Auth Backends

This endpoint lists all enabled auth backends.

Method	Path	Produces
GET	/sys/auth	200 application/json

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    https://vault.rocks/v1/sys/auth

Sample Response

{
  "github/": {
    "type": "github",
    "description": "GitHub auth"
  },
  "token/": {
    "config": {
      "default_lease_ttl": 0,
      "max_lease_ttl": 0
    },
    "description": "token based credentials",
    "type": "token"
  }
}

Mount Auth Backend

This endpoint enables a new auth backend. After mounting, the auth backend can be accessed and configured via the auth path specified as part of the URL. This auth path will be nested under the auth prefix.

For example, mounting the "foo" auth backend will make it accessible at /auth/foo.

• sudo required – This endpoint requires sudo capability in addition to any path-specific capabilities.

Method	Path	Produces
POST	/sys/auth/:path	204 (empty body)

Parameters

• path (string: <required>) – Specifies the path in which to mount the auth backend. This is part of the request URL.

• description (string: "") – Specifies a human-friendly description of the auth backend.

• type (string: <required>) – Specifies the name of the authentication backend type, such as "github" or "token".

Additionally, the following options are allowed in Vault open-source, but relevant functionality is only supported in Vault Enterprise:

• local (bool: false) – Specifies if the auth backend is a local mount
  only. Local mounts are not replicated nor (if a secondary) removed by replication.

Sample Payload

{
  "type": "github",
  "description": "Login with GitHub"
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \

{
  "default_lease_ttl": 3600,
  "max_lease_ttl": 7200
