DESCRIPTION
This tool is part of the samba(7) suite.
The pdbedit program is used to manage the users accounts stored in the sam database and
can only be run by root.
The pdbedit tool uses the passdb modular interface and is independent from the kind of
users database used (currently there are smbpasswd, ldap, nis+ and tdb based and more can
be added without changing the tool).
There are five main ways to use pdbedit: adding a user account, removing a user account,
modifying a user account, listing user accounts, importing users accounts.
OPTIONS
-L|--list
This option lists all the user accounts present in the users database. This option
prints a list of user/uid pairs separated by the ':' character.
Example: pdbedit -L
sorce:500:Simo Sorce
samba:45:Test User
-v|--verbose
This option enables the verbose listing format. It causes pdbedit to list the users in
the database, printing out the account fields in a descriptive format. Used together
with -w also shows passwords hashes.
Example: pdbedit -L -v
---------------
username: sorce
user ID/Group: 500/500
user RID/GRID: 2000/2001
Full Name: Simo Sorce
Home Directory: \\BERSERKER\sorce
HomeDir Drive: H:
Logon Script: \\BERSERKER\netlogon\sorce.bat
Profile Path: \\BERSERKER\profile
---------------
username: samba
user ID/Group: 45/45
user RID/GRID: 1090/1091
Full Name: Test User
Home Directory: \\BERSERKER\samba
HomeDir Drive:
Logon Script:
Profile Path: \\BERSERKER\profile
-w|--smbpasswd-style
This option sets the "smbpasswd" listing format. It will make pdbedit list the users
in the database, printing out the account fields in a format compatible with the
smbpasswd file format. (see the smbpasswd(5) for details). Instead used together with
(-v) displays the passwords hashes in verbose output.
Example: pdbedit -L -w
sorce:500:508818B733CE64BEAAD3B435B51404EE:

-u|--user username
This option specifies the username to be used for the operation requested (listing,
adding, removing). It is required in add, remove and modify operations and optional in
list operations.
-f|--fullname fullname
This option can be used while adding or modifying a user account. It will specify the
user's full name.
Example: -f "Simo Sorce"
-h|--homedir homedir
This option can be used while adding or modifying a user account. It will specify the
user's home directory network path.
Example: -h "\\\\BERSERKER\\sorce"
-D|--drive drive
This option can be used while adding or modifying a user account. It will specify the
windows drive letter to be used to map the home directory.
Example: -D "H:"
-S|--script script
This option can be used while adding or modifying a user account. It will specify the
user's logon script path.
Example: -S "\\\\BERSERKER\\netlogon\\sorce.bat"
--set-nt-hash
This option can be used while modifying a user account. It will set the user's
password using the nt-hash value given as hexadecimal string. Useful to synchronize
passwords.
Example: --set-nt-hash 8846F7EAEE8FB117AD06BDD830B7586C
-p|--profile profile
This option can be used while adding or modifying a user account. It will specify the
user's profile directory.
Example: -p "\\\\BERSERKER\\netlogon"
-M|'--machine SID' SID|rid
This option can be used while adding or modifying a machine account. It will specify
the machines' new primary group SID (Security Identifier) or rid.
Example: -M S-1-5-21-2447931902-1787058256-3961074038-1201
-U|'--user SID' SID|rid
This option can be used while adding or modifying a user account. It will specify the
users' new SID (Security Identifier) or rid.
Example: -U S-1-5-21-2447931902-1787058256-3961074038-5004
Example: '--user SID' S-1-5-21-2447931902-1787058256-3961074038-5004
Example: -U 5004
Example: '--user SID' 5004
-c|--account-control account-control
This option can be used while adding or modifying a user account. It will specify the
users' account control property. Possible flags are listed below.
• N: No password required
• D: Account disabled
• H: Home directory required
• T: Temporary duplicate of other account
• U: Regular user account
• M: MNS logon user account
• W: Workstation Trust Account
• S: Server Trust Account
• L: Automatic Locking
• X: Password does not expire
• I: Domain Trust Account
Example: -c "[X ]"
-K|--kickoff-time
This option is used to modify the kickoff time for a certain user. Use "never" as
argument to set the kickoff time to unlimited.
Example: pdbedit -K never user
-a|--create
This option is used to add a user into the database. This command needs a user name
specified with the -u switch. When adding a new user, pdbedit will also ask for the
password to be used.
Example: pdbedit -a -u sorce
new password:
retype new password
Note
pdbedit does not call the unix password synchronization script if unix password
sync has been set. It only updates the data in the Samba user database.
If you wish to add a user and synchronise the password that immediately, use
smbpasswd's -a option.
-t|--password-from-stdin
This option causes pdbedit to read the password from standard input, rather than from
/dev/tty (like the passwd(1) program does). The password has to be submitted twice and
terminated by a newline each.
-r|--modify
This option is used to modify an existing user in the database. This command needs a
user name specified with the -u switch. Other options can be specified to modify the
properties of the specified user. This flag is kept for backwards compatibility, but
it is no longer necessary to specify it.
-m|--machine
This option may only be used in conjunction with the -a option. It will make pdbedit
to add a machine trust account instead of a user account (-u username will provide the
machine name).
Example: pdbedit -a -m -u w2k-wks
-x|--delete
This option causes pdbedit to delete an account from the database. It needs a username
specified with the -u switch.
Example: pdbedit -x -u bob
-i|--import passdb-backend
Use a different passdb backend to retrieve users than the one specified in smb.conf.
Can be used to import data into your local user database.
This option will ease migration from one passdb backend to another.
Example: pdbedit -i smbpasswd:/etc/smbpasswd.old
-e|--export passdb-backend
Exports all currently available users to the specified password database backend.
This option will ease migration from one passdb backend to another and will ease
backing up.
Example: pdbedit -e smbpasswd:/root/samba-users.backup
-g|--group
If you specify -g, then -i in-backend -e out-backend applies to the group mapping
instead of the user database.
This option will ease migration from one passdb backend to another and will ease
backing up.
-b|--backend passdb-backend
Use a different default passdb backend.
Example: pdbedit -b xml:/root/pdb-backup.xml -l
-P|--account-policy account-policy
Display an account policy
Valid policies are: minimum password age, reset count minutes, disconnect time, user
must logon to change password, password history, lockout duration, min password
length, maximum password age and bad lockout attempt.
Example: pdbedit -P "bad lockout attempt"
account policy value for bad lockout attempt is 0
-C|--value account-policy-value
Sets an account policy to a specified value. This option may only be used in
conjunction with the -P option.
Example: pdbedit -P "bad lockout attempt" -C 3
account policy value for bad lockout attempt was 0
account policy value for bad lockout attempt is now 3
-y|--policies
If you specify -y, then -i in-backend -e out-backend applies to the account policies
instead of the user database.
This option will allow one to migrate account policies from their default tdb-store
into a passdb backend, e.g. an LDAP directory server.
Example: pdbedit -y -i tdbsam: -e ldapsam:ldap://my.ldap.host
--force-initialized-passwords
This option forces all users to change their password upon next login.
-N|--account-desc description
This option can be used while adding or modifying a user account. It will specify the
user's description field.
Example: -N "test description"
-Z|--logon-hours-reset
This option can be used while adding or modifying a user account. It will reset the
user's allowed logon hours. A user may login at any time afterwards.
Example: -Z
-z|--bad-password-count-reset
This option can be used while adding or modifying a user account. It will reset the
stored bad login counter from a specified user.
Example: -z
--policies-reset
This option can be used to reset the general password policies stored for a domain to
their default values.
Example: --policies-reset
-I|--domain
This option can be used while adding or modifying a user account. It will specify the
user's domain field.
Example: -I "MYDOMAIN"
--time-format
This option is currently not being used.
-?|--help
Print a summary of command line options.
--usage
Display brief usage message.
-d|--debuglevel=DEBUGLEVEL
level is an integer from 0 to 10. The default value if this parameter is not specified
is 1 for client applications.
The higher this value, the more detail will be logged to the log files about the
activities of the server. At level 0, only critical errors and serious warnings will
be logged. Level 1 is a reasonable level for day-to-day running - it generates a small
amount of information about operations carried out.
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.
Note that specifying this parameter here will override the log level parameter in the
smb.conf file.
--debug-stdout
This will redirect debug output to STDOUT. By default all clients are logging to
STDERR.
--configfile=<configuration file>
The file specified contains the configuration details required by the client. The
information in this file can be general for client and server or only provide client
specific like options such as client smb encrypt. See smb.conf for more information.
The default configuration file name is determined at compile time.
--option=<name>=<value>
Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This
overrides compiled-in defaults and options read from the configuration file. If a name
or a value includes a space, wrap whole --option=name=value into quotes.
-l|--log-basename=logdirectory
Base directory name for log/debug files. The extension ".progname" will be appended
(e.g. log.smbclient, log.smbd, etc...). The log file is never removed by the client.
--leak-report
Enable talloc leak reporting on exit.
--leak-report-full
Enable full talloc leak reporting on exit.
-V|--version
Prints the program version number.
NOTES
This command may be used only by root.
