Request authentication with Kong

Hi,

We are new to Kong and therefore not sure how to tackle this issue.

We have to authenticate our services with a SAML token. Our micro services are behind kong which is running on an EC2. The authentication process should be an independent micro services which validates the token from the request and it’s contents against another system. Instead of a service it could also be some serverless function on a k8s cluster.

We were previously using AWS API gateway and lambda authorizers to tackle the scenario. The authorizer validated the token and took care of the authentication process.

Is there something similar in Kong or is there development on Kong involved? If yes, are there any existing plugin which are similar or any tutorials related.

All help is greatly appreciated.

Thanks
