Samba NULLs out passwords for accounts that have a last password change time of
0 with the assumption that a password last change time of 0 is different than a
default password last change for new accounts. When an account from NT with the
password last change field not set in the SAM is migrated the password last
change time is set to 0 by default. This prevents the account from
authenticating even though it worked OK in the NT domain.
