🫶 DESCRIPTION 🫶

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

The wbinfo program queries and returns information created and used by the winbindd(8) daemon. It's giving middle-man energy, but in a helpful way 💅

And like, real talk: the winbindd(8) daemon must be configured and running for the wbinfo program to be able to return information. No daemon, no info. Periodt. 🚫

💅 OPTIONS 💅

  • -a|--authenticate username%password — Try to authenticate a user via winbindd(8). It checks both authentication methods and reports its results.
Bestie, do NOT be tempted to use this functionality for authentication in third-party applications. Instead use ntlm_auth(1). I'm serious, it's giving "trust me on this one" 😭
  • --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). The whole roster, no gatekeeping 🌈
  • -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. It fails if the specified domain controller cannot be contacted. Like, it will not improvise. 💀
  • --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. The DC lore, basically 🏰
  • --domain name — This parameter sets the domain on which any specified operations will performed. If the special domain name . is used, it represents 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). ⚠️ Like, your RAM is going to feel it, fr fr.
  • -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). 👀 No spontaneous id assignments here.
  • --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. A lil snack-sized help 🍓
  • -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. Vintage vibes, but okay 🕰️
  • --logoff — Logoff a user. Bye bestie 👋
  • --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 Rest 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. And heads up: if the winbindd(8) daemon is not working, wbinfo will always return failure. Every single time. No exceptions, no mercy 😭

✨ AUTHOR ✨

Okay so the lore drop, bestie 📜✨ — the original Samba software and all its related utilities were created by Andrew Tridgell. Iconic behaviour, truly.

Samba is now developed by the Samba Team as an Open Source project, similar to the way the Linux kernel is developed. Community-coded, community-loved, that's the vibe 🫶

  • 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 ✨

And that's the whole page, bestie, we made it to the end and we ate 🔥💖 This one's from Samba 4.24.7, dated 09/09/2026, so if your install says something else, check your version before you @ me 😭 Go forth and query your winbind info with main character energy — periodt 💅🌸
