OpenID Connect Hybrid Flow¶

MWARE IAM supports the OpenID Connect hybrid flow for authentication.

Specifying any of the following response_type values in an authorization request selects the hybrid flow for authentication.

code token
code id_token
code id_token token

To understand how the response_type value specified in an authorization request selects the hybrid flow to be the authentication flow, let's take a look at the following response_type values in detail.

Register a service provider¶

To register your application as a service provider in the MWARE IAM:

Log in to the MWARE IAM Management Console using administrator credentials.
Go to Main > Identity > Service Providers > Add.
Enter a Service Provider Name. Optionally, enter a Description.
Click Register.

Configure the service provider¶

Make the following changes to the created service provider.

Expand Inbound Authentication Configuration > OAuth/OpenID Connect Configuration and click Configure.
Enter the Callback Url.

Note

The Callback Url is the exact location in the service provider's application to which an access token will be sent. This URL should be the URL of the page that the user is redirected to after successful authentication.
Click Add. Note the OAuth Client Key and OAuth Client Secret that appear.

Tip

To configure more advanced configurations, see OAuth/OpenID Connect Configurations.

Try out the flows¶

Let's try out the different OIDC hybrid flows by specifyin the following response types in the authorization request.

Get code and access token¶

This response_type requests a code and an access token from the authorization endpoint.

Use the following authorization request with code token as the response_type.

Request Format

https://<host>:<port>/oauth2/authorize?response_type=code token&client_id=<oauth_client_key>&nonce=asd&redirect_uri=<redirect_uri>&scope=openid

Sample Request

https://localhost:9443/oauth2/authorize?response_type=code token&client_id=N_nhS_UXctKHofSyLju1rbt_Cbwa&nonce=asd&redirect_uri=http://localhost:8080/playground2/oauth2client&scope=openid

You will receive the following sample response upon successful authorization.

http://localhost:8080/playground2/oauth2client#access_token=1940a308-d492-3660-a9f8-46723cc582e9&code=99b34587-5483-374d-8b25-50485498e761&token_type=Bearer&expires_in=299999&session_state=baae9a71cdabe38b4643b9d59bd9f65ffaf5a9b8c453f4256c085e5a1c57e624.-EA3ZqPzLvsk25CKmt56YA

Send the code to the token endpoint using the following curl command to request for an access token, refresh token, and id_token.

Request Format

curl -k -v --basic -u <oauth_client_key>:<oauth_client_secret> -d "grant_type=<grant_type>&code=<code>&redirect_uri=<redirect_uri>" https://<host>:<port>/oauth2/token

Sample Request

You will receive the following response from the token endpoint.

}

There can be instances where you get two access tokens. One from the authorization endpoint and the other from the token endpoint. These two access tokens may or may not be same.

Get code and id token¶

This response_type requests a code and an id_token from the authorization endpoint.

Use the following authorization request with code id_token as the response_type.

Request Format

https://<host>:<port>/oauth2/authorize?response_type=code id_token&client_id=<oauth_client_key>&nonce=asd&redirect_uri=<redirect_uri>&scope=openid

Note

You will not receive an Id Token if the nonce value is a not present in the request.

Optionally, you can decrypt the id_token. It will be similar to the decrypted id_token shown below.

  "nonce": "asd"
}
```
Note

Here, the id_token is required to have a c_hash value.

c_hash is the base64url encoding of the left-most half of a hash of the octets in the ASCII representation of a code value, where the hash algorithm used is the hash algorithm of the alg header parameter of the ID token’s JOSE header.

The c_hash value is mandatory when an id_token is issued with code, and the response_type is equal to code id_token or code id_token token .

You can send the code to the token endpoint to request for an access token, refresh token and id_token. For this you can use the same curl command provided for the code token specified above.

You will receive the following response from the token endpoint.

If there are two id_tokens issued, where one id_token is from authorization endpoint and other is from token endpoint, be sure to perform the neccessary validations, which are based on the OpenID Connect specification.

Get code, access token, and id token¶

This response_type requests a code, an access token, and an id_token from the authorization endpoint.

Use the following authorization request with code id_token token as the response_type.

If there are two id_tokens issued, where one id_token is from authorization endpoint and other is from token endpoint, be sure to perform the neccessary validations, which are based on the OpenID Connect specification.

id_token validations¶

Ensure that the iss and sub claim values are identical in the two id_tokens .
If any one of the ID tokens contain claims about the end user, and are present in both, the values of the claims should be the same in both.
All claims about the authentication event that is present in either should be present in both.
The at_hash and c_hash claims may be omitted from the ID token returned from the token endpoint even when the claims are present in the ID token returned from the authorization endpoint.
