[keycloak-user] Multiple sessions in the same realm

Hi, I'm setting up a client that forces the user to log in even when he/she is already logged in. I'm doing this by editing the Browser authentication flow, as suggested here (https://stackoverflow.com/questions/53048205/how-to-force-login-per-clien...). When I try to log in with a different account to the one I'm already logged in, I get an error: "You are already authenticated as different user X in this session. Please logout first.". I would like to be able to log in with a different account just for this client, without logging out. Is this possible without moving the client to a different realm? Thank you, Asier
