Comment 5 for bug 462626

Documented at <https://wiki.ubuntu.com/KarmicKoala/ReleaseNotes#Windows%207%20domain%20member%20fails%20to%20authenticate%20to%20Ubuntu%209.10%20Samba%20domain%20controller>:

After upgrading a Samba domain controller to Ubuntu 9.10, Windows 7 domain members will not be able to authenticate to it even if their registry settings were modified as outlined in [[http://wiki.samba.org/index.php/Windows7]] prior to joining the Samba domain. A fix for this issue will be provided in a post-release update immediately after the Ubuntu 9.10 release. (Bug:541411)
