Code review comment for ~ahasenack/ubuntu/+source/samba:cosmic-samba-merge-4.8-1778125

What is failing with 4.8.2, and passing with 4.7.6, is this simple construct on a cifs mountpoint:

root@ubuntu:~# echo hello > $(mktemp /mnt/hello.XXXXXX)
-su: $(mktemp /mnt/hello.XXXXXX): Permission denied
root@ubuntu:~# l /mnt/hello.JJocjv
-rw-------+ 1 nobody nogroup 0 Jun 25 17:56 /mnt/hello.JJocjv
root@ubuntu:~#

The share is just:
[tmp]
 comment = Temp Directory
 guest ok = Yes
 path = /tmp
 read only = No

Since it's a guest connection, the user on the server side is effectively nobody/nogroup, so he should be able to write to the file.

I emailed samba@.
