Title:
  Default [homes] share template uses incorrect %S macro.

Status in “samba” package in Ubuntu:
  Invalid
Status in “samba” package in Debian:
  Confirmed

Bug description:
  Binary package hint: samba

  The default smb.conf suggests a rather unhelpful default for the
  'valid users' option in the [homes] section. It's commented out by
  default, but uncommenting the template leads to some unexpected
  behavior.

  (See https://bugzilla.samba.org/show_bug.cgi?id=7766 for some more
  background; that's a related problem which exists upstream.)

  The suggestion is to use %S as a parameter ("valid users = %S"); back
  around 2005, this expanded to the username, meaning that this setting
  enforced that users could only log into their own home share, as
  described. Now, however, it expands to the current service name, which
  is very unlikely to match the username. The configuration incorrectly
  states that %S expands to the username, which is no longer true. Using
  the default configuration leads to confusing failures; the proper
  setting here is to have "valid users = %U" as the default, since %U
  expands to the name of the current user, according to the smb.conf(5)
  manpage.

  This is present in samba 2:3.4.7~dfsg-1ubuntu3.2 on Lucid, at least.
  It was, according to debian/changelog, added in 3.0.22-1ubuntu3, and
  is still present in debian/smb.conf in the current version, 2:3.5.4
  ~dfsg-1ubuntu8, in Maverick. The attached patch against
  debian/smb.conf from the version in Maverick fixes the issue.
