[Samba] How can one set/reset machine account passwords

[Taso Hatzi]

Scenario:

a) Samba with an ldap backend.

b) The ldap database becomes irretrievably corrupted.

c) I roll in a new ldap database from a known good copy.

d) Problem is the passwords for the machine accounts are out of date.

e) Is it possible to coax Samba & the clients (mostly XP) to resynch
their passwords?

f) I want to preserve the client computers SIDs & names.

g) I really don't want to have to rejoin them to the domain

h) I really don't want to have to visit each client computer individually.
