username
This option specifies that the username following should be added to the local 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 smbpasswd file and it is treated like a regular change password command. Note that the default passdb backends require the user to already exist in the system password file (usually /etc/passwd), else the request to add the user will fail.
This option is only available when running smbpasswd as root.
This option is only available when running smbpasswd as root.
-c
This option can be used to specify the path and file name of the smb.conf configuration file when it is important to use other than the default file and / or location.
-x
This option specifies that the username following should be deleted from the local smbpasswd file.
This option is only available when running smbpasswd as root.
This option is only available when running smbpasswd as root.
-d
This option specifies that the username following should be disabled in the local smbpasswd file. This is done by writing a 'D' flag into the account control space in the smbpasswd file. Once this is done all attempts to authenticate via SMB using this username will fail.
If the smbpasswd file is in the 'old' format (pre-Samba 2.0 format) there is no space in the user's password entry to write this information and the command will FAIL. See smbpasswd(5) for details on the 'old' and new password file formats.

This option is only available when running smbpasswd as root.
-e
This option specifies that the username following should be enabled in the local smbpasswd file, if the account was previously disabled. If the account was not disabled this option has no effect. Once the account is enabled then the user will be able to authenticate via SMB once again.
If the smbpasswd file is in the 'old' format, then smbpasswd will FAIL to enable the account. See smbpasswd(5) for details on the 'old' and new password file formats.
This option is only available when running smbpasswd as root.

-D debuglevel
debuglevel is an integer from 0 to 10. The default value if this parameter is not specified is zero.
The higher this value, the more detail will be logged to the log files about the activities of smbpasswd. At level 0, only critical errors and serious warnings will be logged.
Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic.

-n
This option specifies that the username following should have their password set to null (i.e. a blank password) in the local smbpasswd file. This is done by writing the string "NO PASSWORD" as the first part of the first password stored in the smbpasswd file.
Note that to allow users to logon to a Samba server once the password has been set to "NO PASSWORD" in the smbpasswd file the administrator must set the following parameter in the [global] section of the smb.conf file:
null passwords = yes
This option is only available when running smbpasswd as root.

-r remote machine name
This option allows a user to specify what machine they wish to change their password on. Without this parameter smbpasswd defaults to the local host. The remote machine name is the NetBIOS name of the SMB/CIFS server to contact to attempt the password change. This name is resolved into an IP address using the standard name resolution mechanism in all programs of the Samba suite. See the -R name resolve order parameter for details on changing this resolving mechanism.
The username whose password is changed is that of the current UNIX logged on user. See the -U username parameter for details on changing the password for a different username.
Note that if changing a Windows NT Domain password the remote machine specified must be the Primary Domain Controller for the domain (Backup Domain Controllers only have a read-only copy of the user account database and will not allow the password change).
Note that Windows 95/98 do not have a real password database so it is not possible to change passwords specifying a Win95/98 machine as remote machine target.

-R name resolve order
This option allows the user of smbpasswd to determine what name resolution services to use when looking up the NetBIOS name of the host being connected to.
The options are :"lmhosts", "host", "wins" and "bcast". They cause names to be resolved as follows:
The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the smb.conf(5) file the name resolution methods will be attempted in this order.
The options are :"lmhosts", "host", "wins" and "bcast". They cause names to be resolved as follows:
lmhosts: Lookup an IP address in the Samba lmhosts file. If the line in lmhosts has no name type attached to the NetBIOS name (see the lmhosts(5) for details) then any name type matches for lookup.
host: Do a standard host name to IP address resolution, using the system /etc/hosts, NIS, or DNS lookups. This method of name resolution is operating system depended for instance on IRIX or Solaris this may be controlled by the /etc/nsswitch.conf file). Note that this method is only used if the NetBIOS name type being queried is the 0x20 (server) name type, otherwise it is ignored.
wins: Query a name with the IP address listed in the wins server parameter. If no WINS server has been specified this method will be ignored.
bcast: Do a broadcast on each of the known local interfaces listed in the interfaces parameter. This is the least reliable of the name resolution methods as it depends on the target host being on a locally connected subnet.

The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the smb.conf(5) file the name resolution methods will be attempted in this order.
-m
This option tells smbpasswd that the account being changed is a MACHINE account. Currently this is used when Samba is being used as an NT Primary Domain Controller.
This option is only available when running smbpasswd as root.
This option is only available when running smbpasswd as root.
-U username
This option may only be used in conjunction with the -r option. When changing a password on a remote machine it allows the user to specify the user name on that machine whose password will be changed. It is present to allow users who have different user names on different systems to change these passwords.
-h
This option prints the help string for smbpasswd, selecting the correct one for running as root or as an ordinary user.
-s
This option causes smbpasswd to be silent (i.e. not issue prompts) and to read its old and new passwords from standard input, rather than from /dev/tty (like the passwd(1) program does). This option is to aid people writing scripts to drive smbpasswd
-w password
This parameter is only available if Samba has been compiled with LDAP support. The -w switch is used to specify the password to be used with the ldap admin dn. Note that the password is stored in the secrets.tdb and is keyed off of the admin's DN. This means that if the value of ldap admin dn ever changes, the password will need to be manually updated as well.
-W
NOTE: This option is same as "-w" except that the password should be entered using stdin.
This parameter is only available if Samba has been compiled with LDAP support. The -W switch is used to specify the password to be used with the ldap admin dn.

-i
This option tells smbpasswd that the account being changed is an interdomain trust account. Currently this is used when Samba is being used as an NT Primary Domain Controller. The account contains the info about another trusted domain.
This option is only available when running smbpasswd as root.
This option is only available when running smbpasswd as root.
-L
Run in local mode.
username
This specifies the username for all of the root only options to operate on. Only root can specify this parameter as only root has the permission needed to modify attributes directly in the local smbpasswd file.
EXAMPLES
echo -en "password\npassword\n" | smbpasswd -s -a username
