[Bug 250090] [NEW] winbind upgrade breaks smbusers

[tonyw]

Public bug reported:

Applying the recent upgrade to winbind (3.0.28a-1ubuntu4.4) broke access
to samba shares from both Windows and Linux Clients when the username is
listed in smbusers. Removing the winbind package on the server fixed the
problem and restored access.

The Server is running XUbuntu 8.04 and is fully up-to-date as regards
packages. Samba has both smbusers and smbpasswd files in use and which
are used to map Windows login names (with spaces) to Unix user names.
Samba Unix extensions are not in use on the server in order to avoid
other access control problems (from Linux clients with different UID
mappings). Samba security is set to "user" and the network is organised
as a Workgroup rather than a Windows Domain.

When the upgrade was applied access was refused to both Windows and
Linux clients using user names in the smbusers file. However, access was
possible from both Windows and Linux clients by logging in using an
existing Unix Username on the server. This problem persisted despite
rebooting both client and server.

Inspection of  the upgrade logs showed that Winbind was the only
candidate for causing the problem. Removing Winbind restored access to
clients using smbusers usernames. Conclusion, the Winbind update is
broken.
