[keycloak-user] Does Keycloak's SPNEGO support include fall-back to NTLM in absence of Kerberos?

Good day, For sake of argument, assume that someone has set up a MS Active Directory domain with Kerberos disabled, but NTLM still enabled. In that situation, would a user browsing to a Keycloak-protected application, with LDAP+SPNEGO enabled (against that MS AD system) still allow for Integrated Windows Authentication (auto-login without prompt) to web application? Thanks much, Guy
