OpenIDConnectClientException: Cannot supply client credentials in both the Authentication header and the request-body

Hi @rajnisheu ! My thoughts are as follows.

1. It appears that you're not using composer to install the library. (Thus the missing libs error.)
2. id and secret are place holders for actual value that need to be obtained from your provider. Are you using actual values in this place?

Closing the issue for now. Feel free to re-open if you have additional questions!

I can't find how to re-open this for topic no 2.
There's an issue when un-setting array fields in case of client_secret_basic which is fixed by also un-setting client_id as follows:

# Consider Basic authentication if provider config is set this way
 if (in_array('client_secret_basic', $token_endpoint_auth_methods_supported)) {
   $headers = ['Authorization: Basic ' . base64_encode($this->clientID . ':' . $this->clientSecret)];
   unset($token_params['client_id']); // unset client_id as well
   unset($token_params['client_secret']);
 }

Could be Okta specific. Will run tests with other providers.
Re topic no 1, adding a line to the documentation mentioning dependency on PHPSecLib would great.
Thanks for the library!
