That's not going to be easy.

The native idmap service is called internally from both the zfs +
smbsrv kernel modules, via the kidmap_* interface.

Have you considered adding the winbind-style range mapping you want?
The idmap service already supports a couple different mapping methods.
One more method wouldn't hurt.

I'd also be curious what are the exact circumstances where you saw
idmap change its mapping for some SID to a different ephemeral ID.
Note that TTL expiration does not cause a mapping to be destroyed.  It
only causes it to be re-checked via name lookup rules, etc.
That re-check should not come up with a different ID unless something
in the configuration changed, i.e. a new explicit mapping where one
did not exist before.   If you saw something else happen, that might
be a bug.
