Debian tried it, and disabled this support again because it pulled in too many dependencies: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=941654

Samba 4.12.x has another spotlight backend, elastic search: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=941654

I'm not a macos user so I'm not sure how these are used or which one is best. I'll rely on the community to chime in here.

I use ubuntu 20.04

This instructions help to me for compilation Samba 4.11 (same version in repositories)

And time machine is working.

Not so simple...

Seems to be working with Ubuntu 20.10

$ smbd -b | grep SPOTLIGHT
   WITH_SPOTLIGHT

Indeed 4.12.5 in Groovy has

root@g:~# smbd -b | grep -i spot
   WITH_SPOTLIGHT

But I'm unsure about it, never the less this should be fixed for real since 2:4.13.2+dfsg-1 which fixed
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=956096

This is seen in hirsute:
root@h:~# smbd -b | grep -i spot
   HAVE_SPOTLIGHT_BACKEND_ES
   WITH_SPOTLIGHT

So should be maybe good in 20.10 and surely in 21.04 - setting Fix released.
