Use a dynamic group whitelist with the Org Authorization Server

To use the Group Functions to create a token using a dynamic group whitelist, create a Groups claim on an app. For an Okta Org Authorization Server, you can only create an ID token with a Groups claim.

The Admin Console (Classic UI) is required for this guide.

The upper-left corner of the page should say Classic UI. If it says Developer Console, click the drop-down box to change it to Classic UI.

1. In the Admin Console, from the Applications menu, select Applications, and then select the client application that you want to configure.
2. Navigate to the Sign On tab and click Edit in the OpenID Connect ID Token section.
3. In the Groups claim type section, select Expression.
4. In the Groups claims filter section, leave the default name groups (or add it if the box is empty) and add one of the three functions with the criteria for your dynamic group whitelist. For this example: Groups.startsWith("OKTA", "IT", 10)
5. Click Save.

Request an ID token that contains the Groups claim

To test the full authentication flow that returns an ID token, build your request URL. For the specific steps on building the request URL, receiving the response, and decoding the JWT, see Request a token that contains the claim.

Note: The scopes that you need to include as query parameters are openid and groups.

The resulting URL looks something like this:

curl -X GET
"https://${yourOktaDomain}/oauth2/v1/authorize?client_id=examplefa39J4jXdcCwWA
&response_type=id_token
&scope=openid%20groups
&redirect_uri=https%3A%2F%2FyourRedirectUriHere.com
&state=myState
&nonce=myNonceValue"

The decoded JWT looks something like this:

{
  "sub": "00uixa271s6x7qt8I0h7",
  "ver": 1,
  "iss": "https://${yourOktaDomain}",
  "aud": "0oaoiuhhch8VRtBnC0h7",
  "iat": 1574207471,
  "exp": 1574211071,
  "jti": "ID.3xqAvJ3YTofkkrF0FpapgxFEExGWOEoyhWspO6SFQtA",
  "amr": [
    "pwd",
    "mfa",
    "kba"
  ],
  "idp": "00oixa26ycdNcX0VT0h7",
  "nonce": "UBGW",
  "auth_time": 1574207041,
  "groups": [
    "IT"
  ]
}
