This file format has been evolving with Samba +and has had several different formats in the past\&. +.PP +.SH "FILE FORMAT" +.PP +The format of the smbpasswd file used by Samba 2\&.0 is very similar to +the familiar unix \fBpasswd (5)\fP file\&. It is an ASCII file containing +one line for each user\&. Each field within 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: +.PP +.IP +.IP "\fBname\fP" +.br +.br +.IP +This is the user name\&. It must be a name that already exists +in the standard UNIX passwd file\&. +.IP +.IP "\fBuid\fP" +.br +.br +.IP +This is the UNIX uid\&.

The \fILANMAN\fP hash is created by DES encrypting a well known +string with the users 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 (ie\&. +the password is not \fI"salted"\fP as the UNIX password is)\&. If the +user has a null password this field will contain the characters +\f(CW"NO PASSWORD"\fP as the start of the hex string\&. If the hex string +is equal to 32 \f(CW\'X\'\fP characters then the users account is marked as +\fIdisabled\fP and the user will not be able to log onto the Samba +server\&. +.IP +\fIWARNING !!\fP\&. 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 of the network\&. +For this reason these hashes are known as \fI"plain text equivalent"\fP +and must \fINOT\fP be made available to anyone but the root user\&. To +protect these passwords the \fBsmbpasswd\fP file is placed in a +directory with read and traverse access only to the root user and the +\fBsmbpasswd\fP file itself must be set to be read/write only by root, +with no other access\&. +.IP +.IP "\fBNT Password Hash\fP" +.br +.br +.IP +This is the \fIWindows NT\fP hash of the users password, encoded as 32 +hex digits\&. The \fIWindows NT\fP hash is created by taking the users +password as represented in 16-bit, little-endian UNICODE and then +applying the \fIMD4\fP (internet rfc1321) hashing algorithm to it\&. +.IP +This password hash is considered more secure than the \fBLanman +Password Hash\fP 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 (ie\&. the password is not \fI"salted"\fP as the +UNIX password is)\&. +.IP +\fIWARNING !!\fP\&.

Note that this +will only allow users to log on with no password if the +\fBnull passwords\fP parameter is set +in the \fBsmb\&.conf (5)\fP config file\&. +.IP +.IP o +\fB\'D\'\fP This means the account is diabled and no SMB/CIFS logins +will be allowed for this user\&. +.IP +.IP o +\fB\'W\'\fP This means this account is a \fI"Workstation Trust"\fP account\&. +This kind of account is used in the Samba PDC code stream to allow Windows +NT Workstations and Servers to join a Domain hosted by a Samba PDC\&. +.IP +.IP +Other flags may be added as the code is extended in future\&. The rest of +this field space is filled in with spaces\&. +.IP +.IP "\fBLast Change Time\fP" +.br +.br +.IP +This field consists of the time the account was last modified\&.

New entries added with +\fBsmbpasswd (8)\fP will contain the new fields +in the added accounts however\&. Thus an older \fBsmbpasswd\fP file used +with Samba 2\&.0 may end up with some accounts containing the new fields +and some not\&. +.PP +In order to convert from an old-style \fBsmbpasswd\fP file to a new +style, run the script \fBconvert_smbpasswd\fP, installed in the +Samba \f(CWbin/\fP directory (the same place that the \fBsmbd\fP +and \fBnmbd\fP binaries are installed) as follows: +.PP + +.DS + + + + cat old_smbpasswd_file | convert_smbpasswd > new_smbpasswd_file + + +.DE + + +.PP +The \fBconvert_smbpasswd\fP script reads from stdin and writes to stdout +so as not to overwrite any files by accident\&. +.PP +Once this script has been run, check the contents of the new smbpasswd +file to ensure that it has not been damaged by the conversion script +(which uses \fBawk\fP), and then replace the \f(CW\fP +with the \f(CW\fP\&. +.PP +.SH "VERSION" +.PP +This man page is correct for version 2\&.0 of the Samba suite\&. +.PP +.SH "SEE ALSO" +.PP +\fBsmbpasswd (8)\fP, \fBsamba +(7)\fP, and the Internet RFC1321 for details on the MD4 +algorithm\&. +.PP +.SH "AUTHOR" +.PP +The original Samba software and related utilities were created by +Andrew Tridgell (samba-bugs@samba\&.anu\&.edu\&.au)\&.
