This may be an ldap question.  I was looking at the machines info and I
checked on about 5 of them.  For some reason it is showing that the
sambaPwdLastSet has changed in the last couple of days.  Is this supposed
to ever change for machines if you do not remove them from a domain and
then add them back in?  I would think it would always stay the same.

Machines are added by samba with smbldap-useradd -w "%u".
