[Samba] Scripting with smbpasswd

[richard]

Martin I'm not a programmer but my tests revealed the same result as
yours. The encrypted password remains the same if you enter the old
password again. Actually I was trying to use this to advantage by
storing it in a history file for a ten or twelve values and comparing
new to old to produce something like Nt4s password history check.
want to give it a try?
