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:

            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.

--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.
