[Samba] Mac OS Timemachine over SMB

Is it possible to backup Mac OS devices through a Samba share on Samba
4.4.6 on Fedora 24 with Time Machine? I am able to successfully advertise
the share through Avahi, connect to it in Finder, and read/write files. I
am also able to see the share as a destination in Time Machine, but
selecting it shows an error that "The selected network backup disk does not
support the required capabilities. Please choose another network backup

>From my understanding of the Apple documentation found here, I think that
the current version of Samba satisfies most of the requirements with
vfs_fruit but I would appreciate some confirmation:

- AAPL Create Context extension with F_FULLSYNC (I believe this is
supported by vfs_fruit)

Below is a copy of my SMB configuration (I stood up a VM for testing with
only one share due to a warning in the vfs_fruit documentation about mixing
shares with and without vfs_fruit):
        workgroup = SAMBA
        security = user
        log level = 8
        log file = /var/log/samba.%m

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
        cups options = raw

        ea support = yes
        vfs objects = catia fruit streams_xattr
        fruit:resource = file
        fruit:metadata = netatalk
        fruit:locking = netatalk
        fruit:encoding = native
        fruit:aapl = true
        browseable = Yes
        read only = No
        inherit acls = Yes
        path = /srv
