43a460075a
----------------------------
- removed DOM_RID4
- removed SAMR_UNKNOWN_32
- added SAMR_SET_USERINFO (opcode 0x32)
- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)
- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- added mod_sam21pwd_entry()
- preparing to call mod_sam21pwd_entry()
- added "user session key" to user_struct.dc. this is md4(nt#) and is
needed to decode user's clear-text passwords in SAMR_SET_USERINFO.
- split code out in chgpasswd.c to decode 516 byte password buffers.
