[keycloak-user] Keycloak not falling back in Chrome

Hi,

according to the error, it seems that you switched "Kerberos" 
authenticator to ALTERNATIVE or REQUIRED in "Authentication" tab in 
admin console for Browser flow. However you didn't configure any LDAP or 
Kerberos federation provider for your realm. You need to add the 
federation provider and provide keytab, server principal etc. See docs 
for more details [1].

However, the change seems to have triggered an issue with Keycloak-backed sites. Upon going to a protected page, we get a failure page, but no prompt to enter credentials. Correct me if I'm wrong, but shouldn't Keycloak fall back to prompting for credentials when Kerberos isn't supported for that Client or if the ticket is invalid for some other reason?
