Description

This tool is part of the samba(7) suite.

The wbinfo program queries and returns information created and used by the winbindd(8) daemon.

The winbindd(8) daemon must be configured and running for the wbinfo program to be able to return information.

Options

-a|--authenticate username%password

Attempt to authenticate a user via winbindd(8). This checks both authentication methods and reports its results.

Note
Do not be tempted to use this functionality for authentication in third-party applications. Instead use ntlm_auth(1).

--allocate-gid

Get a new GID out of idmap

--allocate-uid

Get a new UID out of idmap

--all-domains

List all domains (trusted and own domain).

-c|--change-secret

Change the trust account password. May be used in conjunction with domain in order to change interdomain trust account passwords.

--change-secret-at domain-controller

Change the trust account password at a specific domain controller. Fails if the specified domain controller cannot be contacted.

--ccache-save username%password

Store user and password for ccache.

--change-user-password username

Change the password of a user. The old and new password will be prompted.

--dc-info domain

Displays information about the current domain controller for a domain.

--domain name

This parameter sets the domain on which any specified operations will performed. If special domain name '.' is used to represent the current domain to which winbindd(8) belongs. A '*' as the domain name means to enumerate over all domains (NOTE: This can take a long time and use a lot of memory).

-D|--domain-info domain

Show most of the info we have about the specified domain.

--dsgetdcname domain

Find a DC for a domain.

--gid-info gid

Get group info from gid.

--group-info group

Get group info from group name.

-g|--domain-groups

This option will list all groups available in the Windows NT domain for which the samba(7) daemon is operating in. Groups in all trusted domains can be listed with the --domain='*' option. Note that this operation does not assign group ids to any groups that have not already been seen by winbindd(8).

--get-auth-user

Print username and password used by winbindd(8) during session setup to a domain controller. Username and password can be set using --set-auth-user. Only available for root.

--getdcname domain

Get the DC name for the specified domain.

-G|--gid-to-sid gid

Try to convert a UNIX group id to a Windows NT SID. If the gid specified does not refer to one within the idmap gid range then the operation will fail.

-?

Print brief help overview.

-i|--user-info user

Get user info.

-I|--WINS-by-ip ip

The -I option queries winbindd(8) to send a node status request to get the NetBIOS name associated with the IP address specified by the ip parameter.

-K|--krb5auth username%password

Attempt to authenticate a user via Kerberos.

--krb5ccname KRB5CCNAME

Allows one to request a specific kerberos credential cache type used for authentication.

--lanman

Use lanman cryptography for user authentication.

--logoff

Logoff a user.

--logoff-uid UID

Define user uid used during logoff request.

--logoff-user USERNAME

Define username used during logoff request.

--lookup-sids SID1,SID2...

Looks up SIDs. SIDs must be specified as ASCII strings in the traditional Microsoft format. For example, S-1-5-21-1455342024-3071081365-2475485837-500.

-m|--trusted-domains

Produce a list of domains trusted by the Windows NT server winbindd(8) contacts when resolving names. This list does not include the Windows NT domain the server is a Primary Domain Controller for.

-n|--name-to-sid name

The -n option queries winbindd(8) for the SID associated with the name specified. Domain names can be specified before the user name by using the winbind separator character. For example CWDOM1/Administrator refers to the Administrator user in the domain CWDOM1. If no domain is specified then the domain used is the one specified in the smb.conf(5) workgroup parameter.

-N|--WINS-by-name name

The -N option queries winbindd(8) to query the WINS server for the IP address associated with the NetBIOS name specified by the name parameter.

--ntlmv1

Use NTLMv1 cryptography for user authentication.

--ntlmv2

Use NTLMv2 cryptography for user authentication. NTLMv2 is the default method, this option is only maintained for compatibility.

--online-status domain

Display whether winbind currently maintains an active connection or not. An optional domain argument limits the output to the online status of a given domain.

--own-domain

List own domain.

--pam-logon username%password

Attempt to authenticate a user in the same way pam_winbind would do.

-p|--ping

Check whether winbindd(8) is still alive. Prints out either 'succeeded' or 'failed'.

-P|--ping-dc

Issue a no-effect command to our DC. This checks if our secure channel connection to our domain controller is still alive. It has much less impact than wbinfo -t.

-r|--user-groups username

Try to obtain the list of UNIX group ids to which the user belongs. This only works for users defined on a Domain Controller.

There are two scenaries:

User authenticated: When the user has been authenticated, the access token for the user is cached. The correct group memberships are then returned from the cached user token (which can be outdated).
User *NOT* authenticated: The information is queries from the domain controller using the machine account credentials which have limited permissions. The result is normally incomplete and can be also incorrect.

-R|--lookup-rids rid1, rid2, rid3...

Converts RIDs to names. Uses a comma separated list of rids.

--remove-gid-mapping GID,SID

Removes an existing GID to SID mapping from the database.

--remove-uid-mapping UID,SID

Removes an existing UID to SID mapping from the database.

-s|--sid-to-name sid

Use -s to resolve a SID to a name. This is the inverse of the -n option above. SIDs must be specified as ASCII strings in the traditional Microsoft format. For example, S-1-5-21-1455342024-3071081365-2475485837-500.

--separator

Get the active winbind separator.

--sequence

This command has been deprecated. Please use the --online-status option instead.

--set-auth-user username%password

Store username and password used by winbindd(8) during session setup to a domain controller. This enables winbindd to operate in a Windows 2000 domain with Restrict Anonymous turned on (a.k.a. Permissions compatible with Windows 2000 servers only).

--set-gid-mapping GID,SID

Create a GID to SID mapping in the database.

--set-uid-mapping UID,SID

Create a UID to SID mapping in the database.

-S|--sid-to-uid sid

Convert a SID to a UNIX user id. If the SID does not correspond to a UNIX user mapped by winbindd(8) then the operation will fail.

--sid-aliases sid

Get SID aliases for a given SID.

--sid-to-fullname sid

Converts a SID to a full username (DOMAIN\username).

--sids-to-unix-ids sid1,sid2,sid3...

Resolve SIDs to Unix IDs. SIDs must be specified as ASCII strings in the traditional Microsoft format. For example, S-1-5-21-1455342024-3071081365-2475485837-500.

-t|--check-secret

Verify that the workstation trust account created when the Samba server is added to the Windows NT domain is working. May be used in conjunction with domain in order to verify interdomain trust accounts.

-u|--domain-users

This option will list all users available in the Windows NT domain for which the winbindd(8) daemon is operating in. Users in all trusted domains can be listed with the --domain='*' option. Note that this operation does not assign user ids to any users that have not already been seen by winbindd(8) .

--uid-info uid
