.TH SMBPASSWD 8 "08 Jan 1998" "smbpasswd 1.9.18"
.SH NAME
smbpasswd \- change a users smb password in the smbpasswd file.
.SH SYNOPSIS
.B smbpasswd
[
.B \-add
] [
.B username
]
.SH DESCRIPTION
This program is part of the Samba suite.
.B smbpasswd
allows a user to change their encrypted smb password which
is stored in the smbpasswd file (usually kept in the
.I private
directory under the
.I Samba
directory hierarchy. Ordinary users can only run the command
with no options. It will prompt them for their old smb password
and then ask them for their new password twice, to ensure that
the new password was typed correctly. No passwords will
be echoed on the screen whilst being typed. If you have a blank
smb password (specified by the string "NO PASSWORD" in the
smbpasswd file) then just press the <Enter> key when asked
for your old password.
The
.I \-add
and
.I username
options can only be used by a user running as root.
.SH OPTIONS
.I \-add
.RS 3
Specifies that the username following should be added to
the
.I smbpasswd
file, with the new password typed (type <Enter> for the
old password). This option is ignored if the username
following already exists in the
.I smbpasswd
file and it is treated like a regular change password
command. Note that the user to be added
.B must
already exist in the system password file (usually /etc/passwd)
else the request to add the user will fail.
.RE
.I username
.RS 3
You may only specify a username to the smbpasswd command
if you are running as root. Only root should have the
permission to modify other users smb passwords.
.RE
.RE
.SH INSTALLATION
The location of the server and its support files is a matter for individual
system administrators. The following are thus suggestions only.
It is recommended that the
.B smbpasswd
program be installed in the /usr/local/samba/bin directory. This should be
a directory readable by all, writeable only by root. The program should be
executable by all. The program
.B must
be setuid root. This means the permissions should
look like -r-sr-xr-x and the program must be owned by root.
.SH VERSION
This man page is correct for version 1.9.17 of the Samba suite.
These notes will necessarily lag behind
development of the software, so it is possible that your version of
the program has extensions or parameter semantics that differ from or are not
covered by this man page. Please notify these to the address below for
rectification.

.BR smb.conf (5)
.SH
.B BUGS
.RE
The
.B smbpasswd
command is only useful if
.I Samba
has been compiled with encrypted passwords. See the file
.I ENCRYPTION.txt
in the docs directory for details on how to do this.
.SH CREDITS
