NAME

pdbedit - manage the SAM database (Database of Samba Users)

SYNOPSIS

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.

-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.

+o N: No password required

+o D: Account disabled

+o H: Home directory required

+o T: Temporary duplicate of other account

+o U: Regular user account

+o M: MNS logon user account

+o W: Workstation Trust Account

+o S: Server Trust Account

+o L: Automatic Locking

+o X: Password does not expire

+o 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 ${prefix}/etc/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 ${prefix}/etc/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.
