Re: [keycloak-user] KeyCloak Client Credentials pass http header values
Hi,
Thanks for the guidance of using a custom authenticator. Is there a sample
that I can start with?
Also, to your concern about passing sensitive data in HTTP header: I am
asking the client only to send it for the Auth call with the Client Id and
Client Secret. Once, I get that in initial call, I will have it added to
Access Token and then use it going forward. So, the client is not sending
it in every consecutive requests.
Does that make sense or it is still not secure enough?
I really appreciate your response and thanks for your help.
Regards

Hi,
You could try a custom authenticator (maybe extending some of the built-in
authenticators you are using) in order to set notes into the authentication
session.
However, it seems to me you are relying on sensitive information sent
through HTTP headers that can be easily manipulated.
Regards.
