[keycloak-user] User registration outside of Keycloak login form

[Niels Bertram]

Hi Keycloak users,

a strange question for the community ... I have a customer that wants to
have SSO but does not want to use the Keycloak registration screens (themed
or otherwise) but requires the user to be "logged in" to Keycloak after
user registration.

My understanding is that to get the SSO magic to work, a user agent must be
redirected to the Keycloak server so the KEYCLOAK_SESSION? cookie can be
set so that when the user navigates to another SSO enabled site after user
registration, they would be identified in the auth flow of this client. Is
there any way to create a valid SSO session without using the registration
forms of Keycloak server itself? Like doing an XHR request that would
create a user registration and also sets the required server side cookies
in the user agent?

Interested to hear your thoughts.

Many thanks, Niels
