HandleHttpRequest with Kerberos authentication

[#1]

Hello everybody, I have a cluster running with NiFi 1.12.1, secured with self-signed certificates (self-signing keeps me flexible...). I need to allow all users in our company to connect to a WebService at this cluster, set up with a combination of HandleHttpRequest >> {Business Logic} >> HandleHttpResponse. This works fine with SSLContextService enabled, using trust- and keystores with those self-signed certificates. But since we have many users, user authentication via client certificates is not possible, hence I have to use the Kerberos or LDAP infrastructure of our organisation.

My question: Is it possible to run HandleHttpRequest autonomously from the underlying NiFi with an Login Identity Provider using a Kerberos Key Distribution Center to authenticate users? If so - HOW?

Many thanks in advance for thinking about this or even answering, best regards - Gunnar
