Comment 4 for bug 1701073

I have setup 4 reproducer VMs. All running the base OS and installed only required packages for Samba. Here are the results:

SMBClient Xenial Yakkety Zesty Artful
Link to root Y Y Y Y
Link to directory Y Y Y Y
Link to file N N N N

* On Link to file via smbclient, error given is:
NT_STATUS_ACCESS_DENIED opening remote file \opt\smb.conf

Windows Xenial Yakkety Zesty Artful
Link to root Y N N N
Link to directory N N N N
Link to file N N N N

* On Link to root on Windows, the “N” gives error “The directory name is invalid”

Version of Samba on each is:
Xenial 4.3.11+dfsg-0ubuntu0.16.04.7
Yakkety 4.4.5+dfsg-2ubuntu5.6
Zesty 4.5.8+dfsg-0ubuntu0.17.04.2
Artful 4.5.8+dfsg-2ubuntu3

Artful was daily iso downloaded from here on 6/28/2017:
