    I have a guest account to access the ClearPass API clients and REST API. So let's say my guest credentials are 

     

     

    username = myGuestUsername
password = myGuestPassword

     

     

    with the following settings

    When calling the REST API via
     

     

    https://clearpass.company.com:443/api/oauth​

     

    with my client credentials (changed grant type)
     
     

     

    {
"grant_type": "client_credentials",
"client_id": "myAPIClientID",
"client_secret": "theGeneratedAPIClientSecret"
}

     

     
    I get a valid access token. When I change the grant type to username and password and call the REST API with the body 
     

     

    {
"grant_type": "password",
"client_id": "myAPIClientID",
"username": "myGuestUsername",
"password": "myGuestPassword"
}

     

     
    I get a 401 response
     

     

    {
  "type": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html",
  "title": "invalid_grant",
  "status": 401,
  "detail": "Invalid username and password combination"
}

     

     
    I think using the guest credentials is not correct. Which credentials are correct? Is it possible to generate a username and password for the API client?
     
    I can access the API with the client credentials but other users might not have access to the client secret so I want them to log in with user credentials.

    Hi,

     

    Do you have Add the Oauth2 API services ?

    Hey,

    would you mind telling me where I can look it up?

     

    I'm just using ClearPass as a registered guest.

    on Configuration => Services, you need a Oauth2 service
