From 4026ee6b73851ac1dc2c9a77c85f6c3138456c5b Mon Sep 17 00:00:00 2001
From: Pascal Rigaux <pixel@mandriva.com>

Subject: - add authentification in diskdrake --smb (esp. for windows NT) - use
 "credentials=" to put the passwords (ideas and investigations from Stew
 Benedict,  integrated by Pixel, but need testing) Known bug: if you want to
 change the password when there are 2 entries in fstab   using the same
 username=/password=, writing the credentials is done in random order,   =>
 you've got one chance in 2 that the password is changed :-(
