It contains + the username, Unix user id and the SMB hashed passwords of the + user, as well as account flag information and the time the + password was last changed. This file format has been evolving with + Samba and has had several different formats in the past. </P +></DIV +><DIV +CLASS="REFSECT1" +><A +NAME="AEN16" +></A +><H2 +>FILE FORMAT</H2 +><P +>The format of the smbpasswd file used by Samba 2.2 + is very similar to the familiar Unix <TT +CLASS="FILENAME" +>passwd(5)</TT +> + file. It is an ASCII file containing one line for each user. Each field + ithin each line is separated from the next by a colon. Any entry + beginning with '#' is ignored. The smbpasswd file contains the + following information for each user: </P +><P +></P +><DIV +CLASS="VARIABLELIST" +><DL +><DT +>name</DT +><DD +><P +> This is the user name. It must be a name that + already exists in the standard UNIX passwd file. </P +></DD +><DT +>uid</DT +><DD +><P +>This is the UNIX uid. It must match the uid + field for the same user entry in the standard UNIX passwd file. + If this does not match then Samba will refuse to recognize + this smbpasswd file entry as being valid for a user. + </P +></DD +><DT +>Lanman Password Hash</DT +><DD +><P +>This is the LANMAN hash of the user's password, + encoded as 32 hex digits. The LANMAN hash is created by DES + encrypting a well known string with the user's password as the + DES key. This is the same password used by Windows 95/98 machines. + Note that this password hash is regarded as weak as it is + vulnerable to dictionary attacks and if two users choose the + same password this entry will be identical (i.e. the password + is not "salted" as the UNIX password is). If the user has a + null password this field will contain the characters "NO PASSWORD" + as the start of the hex string. If the hex string is equal to + 32 'X' characters then the user's account is marked as + <TT +CLASS="CONSTANT" +>disabled</TT +> and the user will not be able to + log onto the Samba server. </P +><P +><EM +>WARNING !!</EM +> Note that, due to + the challenge-response nature of the SMB/CIFS authentication + protocol, anyone with a knowledge of this password hash will + be able to impersonate the user on the network. For this + reason these hashes are known as <EM +>plain text + equivalents</EM +> and must <EM +>NOT</EM +> be made + available to anyone but the root user. To protect these passwords + the smbpasswd file is placed in a directory with read and + traverse access only to the root user and the smbpasswd file + itself must be set to be read/write only by root, with no + other access. </P +></DD +><DT +>NT Password Hash</DT +><DD +><P +>This is the Windows NT hash of the user's + password, encoded as 32 hex digits. The Windows NT hash is + created by taking the user's password as represented in + 16-bit, little-endian UNICODE and then applying the MD4 + (internet rfc1321) hashing algorithm to it. </P +><P +>This password hash is considered more secure than + the LANMAN Password Hash as it preserves the case of the + password and uses a much higher quality hashing algorithm. + However, it is still the case that if two users choose the same + password this entry will be identical (i.e. the password is + not "salted" as the UNIX password is). </P +><P +><EM +>WARNING !!</EM +>.
