Good point. How common is this use case though ?

In this case, can we ask the customer to add winbindd
essentially to use as a cache manager, or is this
too complex for that use case ?

I'm not directly supporting a customer base here,
so I'm genuinely curious as to how popular this
usage is from people with real customers.
