From fda194255c156ce373d5f195e960bf8712fe4d67 Mon Sep 17 00:00:00 2001 From: Luke Leighton Date: Fri, 19 Mar 1999 05:00:39 +0000 Subject: Beau Kuiper: provided patch so that passwords could only be changed by root if the ACB_PWLOCK bit is set (on a per-user basis). he also added an extra smbpasswd option so that this bit can be modified from command-line.
