Title:
   ACCESS_DENIED with symlinks within a root ("/") share

Status in samba:
  Unknown
Status in samba package in Ubuntu:
  Fix Released
Status in samba source package in Trusty:
  Fix Released
Status in samba source package in Xenial:
  Fix Released
Status in samba source package in Zesty:
  Fix Released

Bug description:
  [Impact]

   * In case of accessing directories chdir to it directly instead of
  its parent directory. This changes how dir symlinks are handled in
  root shares and leads to avoiding the ACCESS_DENIED ISSUE.

  [Test Case]

   1. Prepare smb server with a share:
  [rootshare]
     guest ok = yes
     path = /
     wide links = no
     follow symlinks = yes
   2. On the server:
  mkdir -p /srv/dir
  ln -s /srv/dir /srv/symdir.
   3. Connect from a client:
  smbclient -m smb3 //server/rootshare -c "cd srv\symdir; dir"

  [Regression Potential]

   * When accessing broken symlinks share's base directory is accessed.
  This however seems to be consistent with a pre-fix behavior.

   * One autopkgtest failure has been found, nothing related to samba so
  another bug has been reported (LP: #1713098) against gvfs DEP8 test.
