[keycloak-user] Client Initiated Account Linking doubt

[Tomás García]

I'm looking at this doc:
https://keycloak.gitbooks.io/documentation/server_development/topics/identity-brokering/account-linking.html

And unless your app lives inside a Java servlet guarded by Keycloak,
there's no way to use this feature, right? Due to the hash generation. I
don't see a way to get a client / user session Id since they're internal
stuff in Keycloak associated thanks to the cookie in the user's browser. I
get why it's needed though and I don't see any good alternative right now
for non-servlet apps (OpenID Connect enabled apps made in other languages
for instance)... but it's unfortunate that the doc doesn't clarify it.

Thanks.
