2014-02-01 - New major features!

• New command line tools, both have script parsable output if needed
  • samusrgrp : group membership list / edit
  • sampasswd : user list and password reset
• The commands uses new library functions (libsam.c) for adding and removing users from local groups (group membership), including lower lever SID handling functions.
• Known BUG: If a user is member of no (0) groups, adding it to a group often crashes my program
• Interactive chntpw program changed a bit to then do groups, too. Also easier to quit (more logical looping / menu selections)
• Also note that some command line parameters for chntpw has changed, and it may be better to use sampasswd or samusrgrp in many "automatic" situations.
• Fixed a few smaller issues by myself
• Jacky To got two bugs, one nasty one that could thrash the hive when deleting bottom value in a key, and problem with uninitialized pointers when expanding the hive (would lead to a crash, no corruption I think). Both bugs fixed I hope.
• Steven Shiau submitted a patch making the scripting easier, I decided to go for completely new commands instead. But thank you to all who suggested the same.
• Also thanks to David Collett for catching and fixing bug in REG_MULTI_SZ editing.

v 1.00 140201:

samlib: new library, contains functions for user and group manipulation and low level SID functions. Main features:

• add user to local group
• remove user from local group
• reset user password
• list users and groups, with memberships etc
• SID handling routines (binary to/from string etc) required by group/user edit functions
• updates both group and user correctly, thus finally user "promotion" works!

regedit library:

• Enter buil-in buffer debugger only if in trace mode, else return error or abort()
• Fixed critical bug in del_value which could thrash the hive when removing value in bottom of key.
• And a pointer not reinitialized when buffer reallocated in some cases, fixed. Thanks to Jacky To for reporting those two.
• Some minor adjustments for compiler. A few more utility functions.

sampasswd: new command line utility

• Can be used to reset users passwords from scripts (non interactive)
• Also a few list options, also can supply parsable output

samusrgrp: new command line utility

• edit group memberships (non interactive)
• some list functions, parsable

chntpw:

• Now dedicated to interactive edits
• Now supports full local group membership edits, finally working promotion!
• A lot of users complained about user select being difficult to exit (not understanding to use ! to quit), so after user edit, return is to main menu or program exit (if not -i option)
• User edit (reset, promote etc) now loops instead until q for quit
