[Pkg-samba-maint] Bug#702840: samba: net usershare add fails silently

[Andrew Kane]

Package: samba
Version: 2:3.6.6-5
Severity: grave
Justification: causes non-serious data loss

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
Attempted to use net usershare add to add a guest share to local network.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
'net usershare add Music /media/Archives/music "some music" Everyone:R guest_ok=y'
was the command issued.

   * What was the outcome of this action?
output from net usershare info:

[Music]
path=/media/Archives/shared-music/
comment=some music
usershare_acl=Everyone:R,
guest_ok=y

smbtree shows the server and $print but not Music

on remote machine, thunar cannot see the server but smbtree can (but can't see the Music share)
on local machine, thunar can see server but not Music

   * What outcome did you expect instead?

Expected either the Music share to be visible in thunar and smbtree or net usershare info to not list it.
I did NOT expect the share to actually work, because I've been beating my head against dirt-simple samba configs for 10 years and it has yet to work ONCE.
