[Pkg-samba-maint] Bug#521225: samba: mishandling of mapped read-only attribute causes failed profile sync

[Jeff Sheldon]

Package: samba
Version: 2:3.3.2-1
Severity: critical
Tags: patch
Justification: causes serious data loss


When using roaming profiles with Samba configured as a domain controller, 
Samba bug #6186 can cause data loss if an attempt is made to syncronize a 
roaming profile that includes a file that is marked read-only.

This bug causes our users' roaming profiles to fail a complete sync at
logoff once a file mapped as read-only tries to overwrite a previously
declared read-only file on the Samba server.

A patch is provided with the Samba bug report.
