SAMBA passwd-style files
SAMBA is a free implementation of CIFS/SMB. The password
encryption on Unix and Windows is different, therefore SAMBA must have
his own file where the passwords are encrypted either as NT-Hash and/or as
LAN-Manager-Hash. LAN-Manager-Hashes are weak and shouldn't be used anymore,
NT-Hashes are based on MD4, but no salt is used, therefore users with the
same passwords have the same NT-Hash.
In this file are also stored machine accounts, if the SAMBA server acts as
PDC, such entries ends with $.
