Samba 2.0.20a release notes:
Winbind, security = domain, and Active Directory
Recent security updates for Windows 2000 and Windows 2003 have
changed the fashion in which user and group lists can be obtained
from domain controllers. In short, the RPC mechanisms used by
"security = domain" to retrieve users and groups is not compatible
with these changes. The "security = ads" configuration is not
affected by the Windows protocol changes.
Samba developers are actively working to correct this problem in
the 3.0.21 release. In the meantime, Administrators who are unable
to migrate to "security = ads" and must continue using "security =
domain", can define credentials to be used by winbindd for account
enumeration by executing the following command as root.
REOPENED status has been deprecated. ASSIGNED with keyword of Reopened is preferred.
