Bug Report Checklist

• Have you provided a full/minimal spec to reproduce the issue?
• Have you validated the input using an OpenAPI validator (example)?
• What's the version of OpenAPI Generator used? 4.2.1
• Have you search for related issues/PRs?
• What's the actual output vs expected output?
  Actual: adds all security schemes in middlewares that all get executed.
  Expected: only one security scheme should match.

Description

The generator does not take into account the fact that multiple security schemes are defined as 'OR'. In other words, the generated PHP Slim code will always try to perform all authentication methods simultaneously.

They are added in the middewares like this:

$this->addRoute(..
                $middlewares
            )->setName($operation['operationId']);
