Problem/Justification
Kerberos based encryption is complex to configure and potenially slow. By contrast, the new RPC-over-TLS features available in Linux as of kernel 6.5 are comparatively simple to configure and based on simple x509 certificates. Offering RPC-over-TLS based encryption and mTLS authentication could address the needs in smaller environments.
Impact
This will help ease authentication needs in smaller environments where Kerberos is not desirable.
User Story
I would like to authenticate the servers using TrueNAS as their storage backend by simply distributing the required certificates to them, rather than having to configure Kerberos.
