25
27 This tool is part of the samba(7) suite.
28 The wbinfo program queries and returns information created and used by
30 the winbindd(8) daemon.
31 The winbindd(8) daemon must be configured and running for the wbinfo
33 program to be able to return information.
34
36 -a|--authenticate username%password
37 Attempt to authenticate a user via winbindd(8). This checks both
38 authentication methods and reports its results.
39 Note
41 Do not be tempted to use this functionality for authentication
42 in third-party applications. Instead use ntlm_auth(1).
43 --allocate-gid
45 Get a new GID out of idmap
46 --allocate-uid
48 Get a new UID out of idmap
49 --all-domains
51 List all domains (trusted and own domain).
52 -c|--change-secret
54 Change the trust account password. May be used in conjunction with
55 domain in order to change interdomain trust account passwords.
56 --change-secret-at domain-controller
58 Change the trust account password at a specific domain controller.
59 Fails if the specified domain controller cannot be contacted.
60 --ccache-save username%password
62 Store user and password for ccache.
63 --change-user-password username
65 Change the password of a user. The old and new password will be
66 prompted.
67 --dc-info domain
69 Displays information about the current domain controller for a
70 domain.
71 --domain name
73 This parameter sets the domain on which any specified operations
74 will performed. If special domain name '.' is used to represent the
75 current domain to which winbindd(8) belongs. A '*' as the domain
76 name means to enumerate over all domains (NOTE: This can take a
77 long time and use a lot of memory).
78 -D|--domain-info domain
80 Show most of the info we have about the specified domain.
81 --dsgetdcname domain
83 Find a DC for a domain.
84 --gid-info gid
86 Get group info from gid.
87 --group-info group
89 Get group info from group name.
90 -g|--domain-groups
92 This option will list all groups available in the Windows NT domain
93 for which the samba(7) daemon is operating in. Groups in all
94 trusted domains can be listed with the --domain='*' option. Note
95 that this operation does not assign group ids to any groups that
96 have not already been seen by winbindd(8).
97 --get-auth-user
99 Print username and password used by winbindd(8) during session
100 setup to a domain controller. Username and password can be set
101 using --set-auth-user. Only available for root.
102 --getdcname domain
104 Get the DC name for the specified domain.
105 -G|--gid-to-sid gid
107 Try to convert a UNIX group id to a Windows NT SID. If the gid
108 specified does not refer to one within the idmap gid range then the
109 operation will fail.
110 -?
112 Print brief help overview.
113 -i|--user-info user
115 Get user info.
116 -I|--WINS-by-ip ip
118 The -I option queries winbindd(8) to send a node status request to
119 get the NetBIOS name associated with the IP address specified by
120 the ip parameter.
121 -K|--krb5auth username%password
123 Attempt to authenticate a user via Kerberos.
124 --krb5ccname KRB5CCNAME
126 Allows one to request a specific kerberos credential cache type
127 used for authentication.
128 --lanman
130 Use lanman cryptography for user authentication.
131 --logoff
133 Logoff a user.
134 --logoff-uid UID
136 Define user uid used during logoff request.
137 --logoff-user USERNAME
139 Define username used during logoff request.
140 --lookup-sids SID1,SID2...
142 Looks up SIDs. SIDs must be specified as ASCII strings in the
143 traditional Microsoft format. For example,
144 S-1-5-21-1455342024-3071081365-2475485837-500.
145 -m|--trusted-domains
147 Produce a list of domains trusted by the Windows NT server
148 winbindd(8) contacts when resolving names. This list does not
149 include the Windows NT domain the server is a Primary Domain
150 Controller for.
151 -n|--name-to-sid name
153 The -n option queries winbindd(8) for the SID associated with the
154 name specified. Domain names can be specified before the user name
155 by using the winbind separator character. For example
156 CWDOM1/Administrator refers to the Administrator user in the domain
157 CWDOM1. If no domain is specified then the domain used is the one
158 specified in the smb.conf(5) workgroup parameter.
159 -N|--WINS-by-name name
161 The -N option queries winbindd(8) to query the WINS server for the
162 IP address associated with the NetBIOS name specified by the name
163 parameter.
164 --ntlmv1
166 Use NTLMv1 cryptography for user authentication.
167 --ntlmv2
169 Use NTLMv2 cryptography for user authentication. NTLMv2 is the
170 default method, this option is only maintained for compatibility.
171 --online-status domain
173 Display whether winbind currently maintains an active connection or
174 not. An optional domain argument limits the output to the online
175 status of a given domain.
176 --own-domain
178 List own domain.
179 --pam-logon username%password
181 Attempt to authenticate a user in the same way pam_winbind would
182 do.
183 -p|--ping
185 Check whether winbindd(8) is still alive. Prints out either
186 'succeeded' or 'failed'.
187 -P|--ping-dc
189 Issue a no-effect command to our DC. This checks if our secure
190 channel connection to our domain controller is still alive. It has
191 much less impact than wbinfo -t.
192 -r|--user-groups username
194 Try to obtain the list of UNIX group ids to which the user belongs.
195 This only works for users defined on a Domain Controller.
196 There are two scenaries:
198 1. User authenticated: When the user has been
200 authenticated, the access token for the user is cached.
201 The correct group memberships are then returned from the
202 cached user token (which can be outdated).
203 2. User *NOT* authenticated: The information is queries
205 from the domain controller using the machine account
206 credentials which have limited permissions. The result
207 is normally incomplete and can be also incorrect.
208 -R|--lookup-rids rid1, rid2, rid3...
211 Converts RIDs to names. Uses a comma separated list of rids.
212 --remove-gid-mapping GID,SID
214 Removes an existing GID to SID mapping from the database.
215 --remove-uid-mapping UID,SID
217 Removes an existing UID to SID mapping from the database.
218 -s|--sid-to-name sid
220 Use -s to resolve a SID to a name. This is the inverse of the -n
221 option above. SIDs must be specified as ASCII strings in the
222 traditional Microsoft format. For example,
223 S-1-5-21-1455342024-3071081365-2475485837-500.
224 --separator
226 Get the active winbind separator.
227 --sequence
229 This command has been deprecated. Please use the --online-status
230 option instead.
231 --set-auth-user username%password
233 Store username and password used by winbindd(8) during session
234 setup to a domain controller. This enables winbindd to operate in a
235 Windows 2000 domain with Restrict Anonymous turned on (a.k.a.
236 Permissions compatible with Windows 2000 servers only).
237 --set-gid-mapping GID,SID
239 Create a GID to SID mapping in the database.
240 --set-uid-mapping UID,SID
242 Create a UID to SID mapping in the database.
243 -S|--sid-to-uid sid
245 Convert a SID to a UNIX user id. If the SID does not correspond to
246 a UNIX user mapped by winbindd(8) then the operation will fail.
247 --sid-aliases sid
249 Get SID aliases for a given SID.
250 --sid-to-fullname sid
252 Converts a SID to a full username (DOMAIN\username).
253 --sids-to-unix-ids sid1,sid2,sid3...
255 Resolve SIDs to Unix IDs. SIDs must be specified as ASCII strings
256 in the traditional Microsoft format. For example,
257 S-1-5-21-1455342024-3071081365-2475485837-500.
258 -t|--check-secret
260 Verify that the workstation trust account created when the Samba
261 server is added to the Windows NT domain is working. May be used in
262 conjunction with domain in order to verify interdomain trust
263 accounts.
264 -u|--domain-users
266 This option will list all users available in the Windows NT domain
267 for which the winbindd(8) daemon is operating in. Users in all
268 trusted domains can be listed with the --domain='*' option. Note
269 that this operation does not assign user ids to any users that have
270 not already been seen by winbindd(8) .
271 --uid-info uid
273 Get user info for the user connected to user id UID.
274 --usage
276 Print brief help overview.
277 --user-domgroups sid
279 Get user domain groups.
280 --user-sidinfo sid
282 Get user info by sid.
283 --user-sids sid
285 Get user group SIDs for user.
286 -U|--uid-to-sid uid
288 Try to convert a UNIX user id to a Windows NT SID. If the uid
289 specified does not refer to one within the idmap range then the
290 operation will fail.
291 --verbose
293 Print additional information about the query results.
294 -Y|--sid-to-gid sid
296 Convert a SID to a UNIX group id. If the SID does not correspond to
297 a UNIX group mapped by winbindd(8) then the operation will fail.
298 -V|--version
300 Prints the program version number.
301 -?|--help
303 Print a summary of command line options.
304 --usage
306 Display brief usage message.
307
309 The wbinfo program returns 0 if the operation succeeded, or 1 if the
310 operation failed. If the winbindd(8) daemon is not working wbinfo will
311 always return failure.

317 winbindd(8) and ntlm_auth(1)
318
320 The original Samba software and related utilities were created by
321 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
322 Source project similar to the way the Linux kernel is developed.
323 wbinfo and winbindd were written by Tim Potter.
325 The conversion to DocBook for Samba 2.2 was done by Gerald Carter. The
327 conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander
328 Bokovoy.
