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, modifing 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.

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)

Example: pdbedit -L -w 

sorce:500:508818B733CE64BEAAD3B435B51404EE:
          D2A2418EFC466A8A0F6B1DBB5C3DB80C:
          [UX         ]:LCT-00000000:
samba:45:0F2B255F7B67A7A9AAD3B435B51404EE:
          BC281CE3F53B6A5146629CD4751D3490:
          [UX         ]:LCT-3BFA1E8D:

-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 modifing 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 modifing 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 modifing 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 modifing a user account. It will specify the user's logon script path.

Example: -S "\\\\BERSERKER\\netlogon\\sorce.bat"

-p|--profile profile

This option can be used while adding or modifing 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 syncronisation script if m[blue]unix password syncm[] 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 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 modifing 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 modifing 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 modifing 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 modifing a user account. It will specify the user's domain field.

Example: -I "MYDOMAIN"

--time-format

This option is currently not being used.

-h|--help

Print a summary of command line options.

-d|--debuglevel=level

level is an integer from 0 to 10. The default value if this parameter is not specified is 0.

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 m[blue]smb.conf.5.html#m[] parameter in the smb.conf file.

-V|--version

Prints the program version number.

-s|--configfile <configuration file>

The file specified contains the configuration details required by the server. The information in this file includes server-specific information such as what printcap file to use, as well as descriptions of all the services that the server is to provide. See smb.conf for more information. The default configuration file name is determined at compile time.

-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.
 

NOTES

This command may be used only by root.
