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 specificied 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:

1. 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).

2. 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
Get user info for the user connected to user id UID.

--usage
Print brief help overview.

--user-domgroups sid
Get user domain groups.

--user-sidinfo sid
Get user info by sid.

--user-sids sid
Get user group SIDs for user.

-U|--uid-to-sid uid
Try to convert a UNIX user id to a Windows NT SID. If the uid
specified does not refer to one within the idmap range then the
operation will fail.

--verbose
Print additional information about the query results.

-Y|--sid-to-gid sid
Convert a SID to a UNIX group id. If the SID does not correspond
to a UNIX group mapped by winbindd(8) then the operation will
fail.

-V|--version
Prints the program version number.

-?|--help
Print a summary of command line options.

--usage
Display brief usage message.

EXIT STATUS

The wbinfo program returns 0 if the operation succeeded, or 1 if the
operation failed. If the winbindd(8) daemon is not working wbinfo
will always return failure.
