* More performant winbindd.
* Support for migrating from a Windows NT4 domain to a Samba domain
and maintaining user, group, and domain SIDs.

LDAP directory for storing SID-to-uid/gid mappings.

adduser and deluser scripts into ${PKG_SYSCONFDIR} that are capable of
dealing with usernames containing a "$". These scripts basically
accept the same options as useradd/userdel. They're meant to be used
in "add user script" and "delete user script" to deal with samba
machine accounts.
