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:
                  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 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.

NOTES

This command may be used only by root.
