Examples include thename-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 domainis generally mapped. See also baseDN.The authentication information that the client software sends alongwith each request to a naming server. This information verifies theidentity of a user or machine.A key used to encipher and decipher data intended for programs thatperform encryption. Contrast with key encrypting key.A commonly used, highly sophisticated algorithm developed by theU.S. National Bureau of Standards for encrypting and decrypting data.See also SUN-DES-1.For the N2L service, a databaseID is an alias for a group of mapscontaining NIS entries of the same format (having the same mappingsto 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 four8-bit numbers written in base 10 with periods (dots) separating them.Used to represent IP addresses in the Internet as in: 192.67.67.20.See data encryption standard (DES).(1) An LDAP directory is a container for LDAP objects. In UNIX, acontainer for files and subdirectories.A local file used to store data associated with directory objects.The DIT is the distributed directory structure for a given network. Bydefault, Solaris LDAP clients access the information assuming that theDIT has a given structure. For each domain supported by the LDAPserver, there is an assumed subtree with an assumed structure.A distinguished name is an entry in an X.500 directory informationbase (DIB) composed of selected attributes from each entry in the treealong a path leading from the root down to the named entry.See directory information tree.A distinguished name in LDAP. A tree-like structured addressingscheme of the LDAP directory which gives a unique name to eachLDAP entry.See Domain Name System.An NIS server or an NIS+ server with NIS compatibility set forwardsrequests it cannot answer to DNS servers.298 System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) • January 2005
