  Review Web Service Configuration:

  Change Authentication Method: If the user type cannot be changed, consider changing the authentication method in the web service configuration to one that is supported by the user type.
  User Authorizations: Ensure that the user has the necessary authorizations to access the web service and use the specified authentication method.
  Testing with Different User: If possible, test the web service with a different user type that is known to support the required authentication method.
