Hi everyone, so I've built a custom kerberos authenticator which should, depending on a querystring, not automatically login. So, when I add &login=manual to the url, kerberos authenticator starts, checks, and stops. Now everything is fine when I use this authenticator under normal conditions, in one tab, but: - As a dev, I sometimes have different tabs with different environments open. e.g. http://myapp-local, http://myapp-dev - these apps are different clients in keycloak as well, e.g. my-webapp-local, my-webapp-dev Now I get logged in via kerberos in myapp-local, logout in myapp-test and try to login with different credentials manually in myapp-test. Then, the AuthenticationProcessor raises the following exception when doing this with kerberos login-enabled browsers (chrome, ie): ===================== 2018-02-28 09:57:12,236 WARN

request to identity provider" errormsg. When doing the same thing in firefox (no kerberos, manual login, open 2 tabs in 2 different environments and login with different users), I get at least the errormsg "You are already authenticated as different user [name] in this session. Please logout first." So, my questions are: - Why is this not possible? - Is there anything I can do (having a custom authenticator for kerberos/AD and a custom userstorageprovider for applicationdb) to make it possible to have different users logged in in different tabs for different kc-clients in the same realm? - More specifically: Is there a possibility to use the AuthenticationProcessor in an SPI without having to make a custom keycloakbuild and remove the check in line 246/setAuthenticatedUser, or does this mess up the whole authentication session? Would be great to get a hint here. Thanks!
