18 This tool is part of the samba(7) suite.
19 The pdbedit program is used to manage the users accounts stored in the
21 sam database and can only be run by root.
22 The pdbedit tool uses the passdb modular interface and is independent
24 from the kind of users database used (currently there are smbpasswd,
25 ldap, nis+ and tdb based and more can be added without changing the
26 tool).
27 There are five main ways to use pdbedit: adding a user account,
29 removing a user account, modifying a user account, listing user
30 accounts, importing users accounts.
31
33 -L|--list
34 This option lists all the user accounts present in the users
35 database. This option prints a list of user/uid pairs separated by
36 the ':' character.
37 Example: pdbedit -L
39 sorce:500:Simo Sorce
41 samba:45:Test User
42 -v|--verbose
44 This option enables the verbose listing format. It causes pdbedit
45 to list the users in the database, printing out the account fields
46 in a descriptive format. Used together with -w also shows passwords
47 hashes.
48 Example: pdbedit -L -v
50 ---------------
52 username: sorce
53 user ID/Group: 500/500
54 user RID/GRID: 2000/2001
55 Full Name: Simo Sorce
56 Home Directory: \\BERSERKER\sorce
57 HomeDir Drive: H:
58 Logon Script: \\BERSERKER\netlogon\sorce.bat
59 Profile Path: \\BERSERKER\profile
60 ---------------
61 username: samba
62 user ID/Group: 45/45
63 user RID/GRID: 1090/1091
64 Full Name: Test User
65 Home Directory: \\BERSERKER\samba
66 HomeDir Drive:
67 Logon Script:
68 Profile Path: \\BERSERKER\profile
69 -w|--smbpasswd-style
71 This option sets the "smbpasswd" listing format. It will make
72 pdbedit list the users in the database, printing out the account
73 fields in a format compatible with the smbpasswd file format. (see
74 the smbpasswd(5) for details). Instead used together with (-v)
75 displays the passwords hashes in verbose output.
76 Example: pdbedit -L -w

113 Example: -S "\\\\BERSERKER\\netlogon\\sorce.bat"
115 --set-nt-hash
117 This option can be used while modifying a user account. It will set
118 the user's password using the nt-hash value given as hexadecimal
119 string. Useful to synchronize passwords.
120 Example: --set-nt-hash 8846F7EAEE8FB117AD06BDD830B7586C
122 -p|--profile profile
124 This option can be used while adding or modifying a user account.
125 It will specify the user's profile directory.
126 Example: -p "\\\\BERSERKER\\netlogon"
128 -M|'--machine SID' SID|rid
130 This option can be used while adding or modifying a machine
131 account. It will specify the machines' new primary group SID
132 (Security Identifier) or rid.
133 Example: -M S-1-5-21-2447931902-1787058256-3961074038-1201

146 Example: '--user SID' 5004
148 -c|--account-control account-control
150 This option can be used while adding or modifying a user account.
151 It will specify the users' account control property. Possible flags
152 are listed below.
153 · N: No password required
156 · D: Account disabled
158 · H: Home directory required
160 · T: Temporary duplicate of other account
162 · U: Regular user account

179 -K|--kickoff-time
181 This option is used to modify the kickoff time for a certain user.
182 Use "never" as argument to set the kickoff time to unlimited.
183 Example: pdbedit -K never user
185 -a|--create
187 This option is used to add a user into the database. This command
188 needs a user name specified with the -u switch. When adding a new
189 user, pdbedit will also ask for the password to be used.
190 Example: pdbedit -a -u sorce
192 new password:
194 retype new password
195 Note
198 pdbedit does not call the unix password synchronization script
199 if unix password sync has been set. It only updates the data in
200 the Samba user database.
201 If you wish to add a user and synchronise the password that
203 immediately, use smbpasswd's -a option.
204 -t|--password-from-stdin
206 This option causes pdbedit to read the password from standard
207 input, rather than from /dev/tty (like the passwd(1) program does).
208 The password has to be submitted twice and terminated by a newline
209 each.
210 -r|--modify
212 This option is used to modify an existing user in the database.
213 This command needs a user name specified with the -u switch. Other
214 options can be specified to modify the properties of the specified
215 user. This flag is kept for backwards compatibility, but it is no
216 longer necessary to specify it.
217 -m|--machine
219 This option may only be used in conjunction with the -a option. It
220 will make pdbedit to add a machine trust account instead of a user
221 account (-u username will provide the machine name).
222 Example: pdbedit -a -m -u w2k-wks
224 -x|--delete
226 This option causes pdbedit to delete an account from the database.
227 It needs a username specified with the -u switch.
228 Example: pdbedit -x -u bob
230 -i|--import passdb-backend
232 Use a different passdb backend to retrieve users than the one
233 specified in smb.conf. Can be used to import data into your local
234 user database.
235 This option will ease migration from one passdb backend to another.
237 Example: pdbedit -i smbpasswd:/etc/smbpasswd.old
239 -e|--export passdb-backend
241 Exports all currently available users to the specified password
242 database backend.
243 This option will ease migration from one passdb backend to another
245 and will ease backing up.
246 Example: pdbedit -e smbpasswd:/root/samba-users.backup
248 -g|--group
250 If you specify -g, then -i in-backend -e out-backend applies to the
251 group mapping instead of the user database.
252 This option will ease migration from one passdb backend to another
254 and will ease backing up.
255 -b|--backend passdb-backend
257 Use a different default passdb backend.
258 Example: pdbedit -b xml:/root/pdb-backup.xml -l
260 -P|--account-policy account-policy
262 Display an account policy
263 Valid policies are: minimum password age, reset count minutes,
265 disconnect time, user must logon to change password, password
266 history, lockout duration, min password length, maximum password
267 age and bad lockout attempt.
268 Example: pdbedit -P "bad lockout attempt"
270 account policy value for bad lockout attempt is 0
272 -C|--value account-policy-value
274 Sets an account policy to a specified value. This option may only
275 be used in conjunction with the -P option.
276 Example: pdbedit -P "bad lockout attempt" -C 3
278 account policy value for bad lockout attempt was 0
280 account policy value for bad lockout attempt is now 3
281 -y|--policies
283 If you specify -y, then -i in-backend -e out-backend applies to the
284 account policies instead of the user database.
285 This option will allow one to migrate account policies from their
287 default tdb-store into a passdb backend, e.g. an LDAP directory
288 server.
289 Example: pdbedit -y -i tdbsam: -e ldapsam:ldap://my.ldap.host
291 --force-initialized-passwords
293 This option forces all users to change their password upon next
294 login.
295 -N|--account-desc description
297 This option can be used while adding or modifying a user account.
298 It will specify the user's description field.
299 Example: -N "test description"
301 -Z|--logon-hours-reset
303 This option can be used while adding or modifying a user account.
304 It will reset the user's allowed logon hours. A user may login at
305 any time afterwards.
306 Example: -Z
308 -z|--bad-password-count-reset
310 This option can be used while adding or modifying a user account.
311 It will reset the stored bad login counter from a specified user.
312 Example: -z
314 --policies-reset
316 This option can be used to reset the general password policies
317 stored for a domain to their default values.
318 Example: --policies-reset
320 -I|--domain
322 This option can be used while adding or modifying a user account.
323 It will specify the user's domain field.
324 Example: -I "MYDOMAIN"
326 --time-format
328 This option is currently not being used.
329 -?|--help
331 Print a summary of command line options.
332 --usage
334 Display brief usage message.
335 -d|--debuglevel=level
337 level is an integer from 0 to 10. The default value if this
338 parameter is not specified is 0.
339 The higher this value, the more detail will be logged to the log
341 files about the activities of the server. At level 0, only critical
342 errors and serious warnings will be logged. Level 1 is a reasonable
343 level for day-to-day running - it generates a small amount of
344 information about operations carried out.
345 Levels above 1 will generate considerable amounts of log data, and
347 should only be used when investigating a problem. Levels above 3
348 are designed for use only by developers and generate HUGE amounts
349 of log data, most of which is extremely cryptic.
350 Note that specifying this parameter here will override the log
352 level parameter in the smb.conf file.
353 -V|--version
355 Prints the program version number.
356 -s|--configfile=<configuration file>
358 The file specified contains the configuration details required by
359 the server. The information in this file includes server-specific
360 information such as what printcap file to use, as well as
361 descriptions of all the services that the server is to provide. See
362 smb.conf for more information. The default configuration file name
363 is determined at compile time.
364 -l|--log-basename=logdirectory
366 Base directory name for log/debug files. The extension ".progname"
367 will be appended (e.g. log.smbclient, log.smbd, etc...). The log
368 file is never removed by the client.
369 --option=<name>=<value>
371 Set the smb.conf(5) option "<name>" to value "<value>" from the
372 command line. This overrides compiled-in defaults and options read
373 from the configuration file.
374
376 This command may be used only by root.

385 The original Samba software and related utilities were created by
386 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
387 Source project similar to the way the Linux kernel is developed.
388 The pdbedit manpage was written by Simo Sorce and Jelmer Vernooij.
