Hi Guys,
I have implementation of OAuth2 Provider in mule with grant_type client_credentials and I was trying this scenario: instead of passing of the client_id & client_secret as parameter I like it to be in the form of Authorization: Basic having the token Base64encoded (username:password) or (client_id:client_secret).
Right now I'm getting this error message :
Client ID: failed to present a secret and no security provider is configured to validate its credentials
I wonder where can I defined the credentials for this validation. I'm hoping it would be resolved by defining Principal (username:password) but the documentation of Mule doesn't show how to define the principals. Is there anyone who knows how to define principals in mule oauth2 provider config?
I must have missed this part of documentation: clientSecurityProvider validates client credentials, it’s only needed when a client is confidential AND has a client secret. Whenever the client credentials are sent on the authorization header, you need this provider to delegate the authentication.
I applied clientSecurityProvider instead of resourceOwnerSecurityProvider and then assign the principal with the username. Now it works.
Thanks
