NAME wbinfo - Query information from winbind daemon
SYNOPSIS wbinfo [-a user%password] [--all-domains] [--allocate-gid] [--allocate-uid] [-c] [--ccache-save] [--change-user-password] [-D domain] [--dc-info domain] [--domain domain] [--dsgetdcname domain] [-g] [--getdcname domain] [--get-auth-user] [-G gid] [--gid-info gid] [--group-info group] [--help|-?] [-i user] [-I ip] [-K user%password] [--krb5ccname cctype] [--lanman] [--logoff] [--logoff-uid uid] [--logoff-user username] [--lookup-sids] [-m] [-n name] [-N netbios-name] [--ntlmv1] [--ntlmv2] [--online-status] [--own-domain] [-p] [-P|--ping-dc] [--pam-logon user%password] [-r user] [-R|--lookup-rids] [--remove-gid-mapping gid,sid] [--remove-uid-mapping uid,sid] [-s sid] [--separator] [--sequence] [--set-auth-user user%password] [--set-gid-mapping gid,sid] [--set-uid-mapping uid,sid] [-S sid] [--sid-aliases sid] [--sid-to-fullname sid] [--sids-to-unix-ids sidlist] [-t] [-u] [--uid-info uid] [--usage] [--user-domgroups sid] [--user-sidinfo sid] [--user-sids sid] [-U uid] [-V] [--verbose] [-Y sid]
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.
--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 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.
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: 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.
--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.
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.

AUTHOR The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
wbinfo and winbindd were written by Tim Potter.
The conversion to DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
