It provides functionality to the NFSv4 kernel client and server, to which it communicates via upcalls, by translating user and…
idmap_tdb2 – Samba’s idmap_tdb2 Backend for Winbind Description The idmap_tdb2 plugin is a substitute for the default idmap_tdb backend used by winbindd for storing SID/uid/gid mapping tables in clustered environments with Samba and CTDB. In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new…
idmap_tdb – Samba’s idmap_tdb Backend for Winbind Description The idmap_tdb plugin is the default backend used by winbindd for storing SID/uid/gid mapping tables. In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new user and group IDs in order to create new mappings. Idmap…
idmap_sss – SSSSD’s idmap_sss Backend for Winbind Description The idmap_sss module provides a way to call SSSD to map UIDs/GIDs and SIDs. No database is required in this case as the mapping is done by SSSD. Idmap Options range = low – high Defines the available matching uid and gid range for which the backend…
idmap_script – Samba’s idmap_script Backend for Winbind Description The idmap_script plugin is a substitute for the idmap_tdb2 backend used by winbindd for storing SID/uid/gid mapping tables in clustered environments with Samba and CTDB. It is a read only backend that uses a script to perform mapping. It was developed out of the idmap_tdb2 back end…
idmap_rid – Samba’s idmap_rid Backend for Winbind Description The idmap_rid backend provides a way to use an algorithmic mapping scheme to map UIDs/GIDs and SIDs. No database is required in this case as the mapping is deterministic. Note that the idmap_rid module has changed considerably since Samba versions 3.0. and 3.2. Currently, there should to…
idmap_rfc2307 – Samba’s idmap_rfc2307 Backend for Winbind Description The idmap_rfc2307 plugin provides a way for winbind to read id mappings from records in an LDAP server as defined in RFC 2307. The LDAP server can be stand-alone or the LDAP server provided by the AD server. An AD server is always required to provide the…
idmap_nss – Samba’s idmap_nss Backend for Winbind Description The idmap_nss plugin provides a means to map Unix users and groups to Windows accounts and obsoletes the "winbind trusted domains only" smb.conf option. This provides a simple means of ensuring that the SID for a Unix user named jsmith is reported as the one assigned to…
idmap_ldap – Samba’s idmap_ldap Backend for Winbind Description The idmap_ldap plugin provides a means for Winbind to store and retrieve SID/uid/gid mapping tables in an LDAP directory service. In contrast to read only backends like idmap_rid, it is an allocating backend: This means that it needs to allocate new user and group IDs in order…
idmap_hash – DO NOT USE THIS BACKEND Description DO NOT USE THIS PLUGIN The idmap_hash plugin implements a hashing algorithm used to map SIDs for domain users and groups to 31-bit uids and gids, respectively. This plugin also implements the nss_info API and can be used to support a local name mapping files if enabled…
idmap_autorid – Samba’s idmap_autorid Backend for Winbind Description The idmap_autorid backend provides a way to use an algorithmic mapping scheme to map UIDs/GIDs and SIDs that is more deterministic than idmap_tdb and easier to configure than idmap_rid. The module works similar to idmap_rid, but it automatically configures the range to be used for each domain,…
idmap_ad – Samba’s idmap_ad Backend for Winbind Description The idmap_ad plugin provides a way for Winbind to read id mappings from an AD server that uses RFC2307/SFU schema extensions. This module implements only the "idmap" API, and is READONLY. Mappings must be provided in advance by the administrator by adding the uidNumber attributes for users…
* Name idled – provide near real-time updates for IMAP IDLE Synopsis idled [ -C config-file ] Description Idled is a long lived datagram daemon which receives notifications of mailbox changes and signals the appropriate imapd to report the changes to the client. Idled is usually started from master. Idled reads its configuration options out…
ipmiutil_discover – discover IPMI LAN-enabled nodes Synopsis idiscover [-abegisx] Description idiscover is a program that uses IPMI LAN commands to discover any nodes on the LAN that are available, by probing the RMCP port (623.) on those nodes. This utility uses IPMI LAN, so no IPMI drivers are needed. There are three methods that can…
ident – nnrpd ident resolver Synopsis ident [-p port] [-t] Description This program attempts to resolve usernames for nnrpd by using the ident protocol to query the remote host. It contacts the remote host using either IPv4 or IPv6 depending on which protocol was used for the incoming NNTP connection. Options -p port If this…
ipmiutil_delloem – OEM commands for Dell servers Synopsis ipmiutil delloem [-mx -NPRUEFJTVY] commands Description ipmiutil delloem commands is a program that uses Dell OEM IPMI commands to perform platform-specific functions. Options -m 002000 Show FRU for a specific MC (e.g. bus 00, sa 20, lun 00). This could be used for PICMG or ATCA blade…
ipmiutil_dcmi – handle DCMI functions Synopsis ipmiutil dcmi [-admsx -NUPREFTVY] <function> Description This ipmiutil dcmi subcommand handles DCMI command functions according to the DCMI specification. This utility can use either the /dev/ipmi0 driver from OpenIPMI, the /dev/imb driver from Intel, the /dev/ipmikcs driver from valinux, direct user-space IOs, or the IPMI LAN interface if -N….
icupkg – extract or modify an ICU .dat archive Synopsis icupkg [ -h, -?, –help ] [ -tl, –type l | -tb, –type b | -te, –type e ] [ -c, –copyright | -C, –comment comment ] [ -a, –add list ] [ -r, –remove list ] [ -x, –extract list ] [ -l, –list…
iconvconfig – create iconv module configuration cache Synopsis iconvconfig [options] [directory]… Description The iconv(3) function internally uses gconv modules to convert to and from a character set. A configuration file is used to determine the needed modules for a conversion. Loading and parsing such a configuration file would slow down programs that use iconv(3), so…
ipmiutil_config – list, save, and restore BMC configuration parameters Synopsis ipmiutil config [-lpxLNUPREFJTVY] [-r file] [-s file] Description ipmiutil config is a program that uses an IPMI driver to send IPMI commands which list, save and restore BMC configuration parameters for LAN, Serial, PEF, SOL, User, Channel.
