Unsupported grant type curl

The resource owner password or "password" grant type is mostly used in cases where the app is highly trusted. An identity server validates the credentials, and if they are valid, Edge proceeds to mint an access token and returns it to the app. This topic offers a general description and overview of the OAuth 2.

This grant type is intended for highly trusted or privileged apps because the user is required to give their resource server credentials to the app. Typically, the app provides a login screen where the user enters their credentials.

The following flow diagram illustrates the resource owner password grant type flow with Apigee Edge serving as the authorization server. Tip: To see a larger version of this diagram, right-click it and open it in a new tab, or save it and open it in an image viewer.

Here is a summary of the steps required to implement the password grant type where Apigee Edge serves as the authorization server. Prerequisite: The client app must be registered with Apigee Edge to obtain the client ID and client secret keys. See Registering client apps for details. When the app needs to access the user's protected resources for example, the user clicks a button in the appthe user is redirected to a login form.

The app sends an access token request, including the user's credentials, to a GenerateAccessToken endpoint on Apigee Edge. Alternatively, that command could be performed as the following, using the -u option to curl to create the baseencoded Basic Authentication header for you.

The user credentials are contained in the form parameters, while the client credentials are encoded in the HTTP basic authentication header. For a detailed description of this API call, including details about the required Basic Auth header, see the password grant section of " Requesting access tokens and authorization codes ".

Before sending the user's username and password to an identity provider, Edge needs to know that the client app making the request is a valid, trusted app. In some cases, you might wish to validate both the client key and secret. There's a sample proxy that illustrates this allternate technique in the api-platform-samples repository on GitHub. After the client app is validated, you can use a Service Callout or JavaScript policy to call the identity service, sending in the user's credentials.

For example, it could be an LDAP service or any service that you wish to use to validate the credentials. For details on these policies, see Extract Variables policy and JavaScript policy. If the identity service validates the credentials, and returns a response, then Edge will continue processing the request; otherwise, Edge stops processing and returns an error to the client app.

If the credentials are valid, the next processing step is to execute an OAuthV2 policy configured for the password grant type. Here is an example. For detailed reference information on this policy, see OAuthV2 policy.

If this policy succeeds, a response is generated back to the client containing an access token. The response is in JSON format. Here's an example. Now, with a valid access code, the client can make calls to the protected API. In this scenario, requests are made to Apigee Edge the proxyand Edge is responsible for validating the access token before passing the API call along to the target resource server.

Access tokens are passed in an Authorization header. For example:. Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4. For details, see the Google Developers Site Policies. Apigee Edge Private Cloud Latest v4. Earlier Versions v4.

The user pool client makes requests to this endpoint directly and not through the system browser. For more information on the specification see Token Endpoint. Must be a preregistered client in the user pool. The client must be enabled for Amazon Cognito federation. Required if the client is public and does not have a secret. Can be a combination of any custom scopes associated with a client. Any scope requested must be preassociated with the client or it will be ignored at runtime. If the client doesn't request any scopes, the authentication server uses all custom scopes associated with the client.

The refresh token is defined in the specification, but is not currently implemented to be returned from the Token Endpoint. Client authentication failed. Client is not allowed for code grant flow or for refreshing tokens. Javascript is disabled or is unavailable in your browser. Please refer to your browser's Help pages for instructions.

Look in authz-config. It's disabled by default because the password grant is horribly insecure. I am getting a LDAP authorization error now but I believe it has to do with encrypting the password correctly when doing the curl command.
