Just tried with EXACTLY your smb.conf settings. Worked. Next
try: Can you please strace smbd?

Start a network trace according to


The last network traces you sent unfortunately did not show
any relevant traffic, there must be something wrong with
your tcpdump. Please make sure that you see the right
traffic with wireshark before you send that again.

Connect to the share with an explorer window, so that you
get a service smbd. Look up the PID with smbstatus. Then
start another network trace. Please then do a

strace -ttT -p <smbd-pid> -o /tmp/smbd.strace

Then start your test program and do a modification of the
subdir from a command line program. Then stop the strace
with Ctrl-C, stop the network trace and send both.

With best regards,
