Yes, you got the usecase right. <br>

questions come to my mind if i follow this manual

<br>

<span style="background-color:rgb(255,255,255)">1. Will this
take into account a KeycloakConfigResolver that's in place

RSATokenVerifier.verifyToken() seems to get all info it

nope, it won't. This approach is about ignoring the official
adapter, which is triggered by security constraints from web.xml and
works at servlet layer. So in your case, request will be always
passed through servlet layer to REST endpoint when you need to do
programmatic authentication by yourself.<br>
<br>
So you may also need to read the keycloak.json file manually and use
KeycloakDeploymentBuilder.build to read KeycloakDeployment and read
publicKey and realmInfoUrl from there, so you can do
RSATokenVerifier.verifyToken by yourself.<br>

It will be ignored and you will again need to do Basic
Authentication by yourself if you want to support in addition to
Bearer authentication. See BasicAuthRequestAuthenticator for
inspiration. <br>

<div>I though that's why you want programmatic access
because you want to have complete control? In that case
you can remove all security constraints from web.xml and
at your REST endpoints you would do the
authentication/authorization exactly how you want. So at
the beginning of REST endpoint you will do something
like:<br>
<br>
if (request.containsHeader("Authorization: Bearer")) {<br>
do-keycloak-authentication-with-keycloak-access-token();<br>
} else {<br>
do-legacy-authentication-or-whatever-based-on-yourAPI-keys-stuff();<br>
} <br>
<br>
Or maybe I don't understand the usecase?<span

about securing REST endpoints. I saw the
BearerTokenRequestAuthenticator code.<br>

The problem is how to conditionally
authenticate requests using a custom
authentication method that does not rely on
keycloak users, roles, clients etc. Would a
custom MyCustomRequestAuthenticator do the
job? Are there any examples on that?
Ideally, an authenticator running inside the
adapter that would compare against values in
the application database wound to the job. <br>

<div>If you're focused on security for REST
endpoints, I think it is quite easy to do
it programaticaly. You may just need to
parse the "Authorization" header from
request with bearer token and verify it
with RSATokenVerifier.<span

I think i may tackle the issue
for now through the
KeycloakConfigResolver. Maybe
return an empty deployment if
the API Key is in the request.<br>
