User Authentication
The SCIM protocol doesn’t define a method for authenticating a user. The PingOne for Enterprise Directory API uses the OAuth 2.0 Resource Owner Password Credential grant to facilitate user authentication.
To authenticate the user Meredith using her username and password, perform the following request:
curl -v -X POST --user 1234-aaaa-bbbb-5678:eXJzbmVha3kh \
-d "grant_type=password&username=marcher&password=2Federate"
https://directory-api.pingone.com/api/oauth/token
An HTTP 200 OK response signals a successful login. Any other response is a failed authentication attempt.
