|System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) Oracle Solaris 11 Express 11/10|
Application-level naming services are incorporated in applications offering services such as files, mail, and printing. Application-level naming services are bound below enterprise-level naming services. The enterprise-level naming services provide contexts in which contexts of application-level naming services can be bound.
Each LDAP entry consists of a number of named attributes each of which has one or more values.
Also, the N2L service mapping and configuration files each consist of a number of named attributes. Each attribute has one or more values.
The means by which a server can verify a client's identity.
The DN where part of the DIT is rooted. When this is the baseDN for a NIS domains entries it is also referred to as a context.
(1) The client is a principal (machine or user) requesting an naming service from an naming server.
(2) In the client-server model for file systems, the client is a machine that remotely accesses resources of a compute server, such as compute power and large memory capacity.
(3) In the client-server model, the client is an application that accesses services from a “server process.” In this model, the client and the server can run on the same machine or on separate machines.
A common way to describe network services and the model user processes (programs) of those services. Examples include the name-server/name-resolver paradigm of the Domain Name System (DNS). See also client.
For the N2L service, a context is something under which a NIS domain is generally mapped. See also baseDN.
For the N2L service, a databaseID is an alias for a group of maps containing NIS entries of the same format (having the same mappings to LDAP). The maps might have differing keys.
DBM is the database originally used to store NIS maps.
The syntactic representation for a 32-bit integer that consists of four 8-bit numbers written in base 10 with periods (dots) separating them. Used to represent IP addresses in the Internet as in: 188.8.131.52.
The DIT is the distributed directory structure for a given network. By default, Solaris LDAP clients access the information assuming that the DIT has a given structure. For each domain supported by the LDAP server, there is an assumed subtree with an assumed structure.
See directory information tree.
A distinguished name in LDAP. A tree-like structured addressing scheme of the LDAP directory which gives a unique name to each LDAP entry.
(1) In the Internet, a part of a naming hierarchy usually corresponding to a Local Area Network (LAN) or Wide Area Network (WAN) or a portion of such a network. Syntactically, an Internet domain name consists of a sequence of names (labels) separated by periods (dots). For example, sales.doc.com.
(2) In International Organization for Standardization's open systems interconnection (OSI), “domain” is generally used as an administrative partition of a complex distributed system, as in MHS private management domain (PRMD), and directory management domain (DMD).
The name assigned to a group of systems on a local network that share DNS administrative files. The domain name is required for the network information service database to work properly. See also domain.
A service that provides the naming policy and mechanisms for mapping domain and machine names to addresses outside of the enterprise, such as those on the Internet. DNS is the network information service used by the Internet.
The means by which the privacy of data is protected.
An “enterprise-level” network can be a single Local Area Network (LAN) communicating over cables, infra-red beams, or radio broadcast; or a cluster of two or more LANs linked together by cable or direct phone connections. Within an enterprise-level network, every machine is able to communicate with every other machine without reference to a global naming service such as DNS or X.500/LDAP.
A NIS map entry might consist of a number of components and separator characters. As part of the N2L service mapping process the entry is first broken down into a number of named fields.
A global naming service identifies (names) those enterprise-level networks around the world that are linked together by phone, satellite, or other communication systems. This world-wide collection of linked networks is known as the “Internet.” In addition to naming networks, a global naming service also identifies individual machines and users within a given network.
Lightweight Directory Access Protocol is a standard, extensible directory access protocol used by LDAP naming service clients and servers to communicate with each other.
The process of converting NIS entries to or from DIT entries. This process is controlled by a mapping file.
The server that maintains the master copy of the network information service database for a particular domain. Namespace changes are always made to the naming service database kept by the domain's master server. Each domain has only one master server.
NIS-to-LDAP server. An NIS master server that has been reconfigured as an N2L server by using the N2L service. Reconfiguration includes replacing NIS daemons and adding new configuration files.
(2) The set of all names in a naming system.
NDBM is an improved version of DBM.
A distributed network information service containing key information about the systems and the users on the network. The NIS database is stored on the master server and all the replica or slave servers.
A file used by NIS that holds information of a particular type, for example, the password entries of all users on a network or the names of all host machines on a network. Programs that are part of the NIS service query these maps. See also NIS.
A client_info table or a client_info file. Preferred server lists specify the preferred servers for a client or domain.
The private component of a pair of mathematically generated numbers, which, when combined with a private key, generates the DES key. The DES key in turn is used to encode and decode information. The private key of the sender is only available to the owner of the key. Every user or machine has its own public and private key pair.
The public component of a pair of mathematically generated numbers, which, when combined with a private key, generates the DES key. The DES key in turn is used to encode and decode information. The public key is available to all users and machines. Every user or machine has their own public and private key pair.
Relative Distinguished Name. One part of a DN.
An easy and popular paradigm for implementing the client-server model of distributed computing. A request is sent to a remote system to execute a designated procedure, using arguments supplied, and the result is returned to the caller.
RFC specifying a mapping of information from the standard NIS maps to DIT entries. By default, the N2L service implements the mapping specified in an updated version RFC 2307bis.
The simple authentication and security layer. A framework for negotiating authentication and security layer semantics in application-layer protocols.
A set of rules defining what types of data can be stored in any given LDAP DIT.
A description of where to look for a given attribute in the DIT. The searchTriple is composed of a 'base dn', 'scope' and 'filter'. This is part of the LDAP URL format as defined in RFC 2255.
(2) In the client-server model for file systems, the server is a machine with computing resources (and is sometimes called the compute server), and large memory capacity. Client machines can remotely access and make use of these resources. In the client-server model for window systems, the server is a process that provides windowing services to an application, or “client process.” In this model, the client and the server can run on the same machine or on separate machines.
(3) A daemon that actually handles the providing of files.
NIS source files
SSL is the secure sockets layer protocol. It is a generic transport-layer security mechanism designed to make application protocols such as LDAP secure.
In LDAP, the distinguished name (DN) of the DIT.
Acronym for Transport Control Protocol/Interface Program. The protocol suite originally developed for the Internet. It is also called the Internet protocol suite. Oracle Solaris networks run on TCP/IP by default.
Yellow Pages. The old name for NIS which is still used within the NIS code.
