Netscape DIRECTORY SERVER 6.2 Installation Manual page 128

DNS Domain Name System. The system used by machines on a network to
associate standard IP addresses (such as 198.93.93.10) with hostnames (such as
). Machines normally get the IP address for a hostname from
www.example.com
a DNS server, or they look it up in tables maintained on their systems.
DNS alias A DNS alias is a hostname that the DNS server knows points to a
different host—specifically a DNS CNAME record. Machines always have one real
name, but they can have one or more aliases. For example, an alias such as
might point to a real machine called
www.[yourdomain].[domain]
where the server currently exists.
realthing.[yourdomain].[domain]
DSGW See Directory Server Gateway (DSGW).
entry A group of lines in the LDIF file that contains information about an object.
entry distribution Method of distributing directory entries across more than one
server in order to scale to support large numbers of entries.
entry ID list Each index that the directory uses is composed of a table of index
keys and matching entry ID lists. The entry ID list is used by the directory to build
a list of candidate entries that may match the client application's search request.
equality index Allows you to search efficiently for entries containing a specific
attribute value.
file extension The section of a filename after the period or dot (.) that typically
defines the type of file (for example, .GIF and .HTML). In the filename
index.html
the file extension is .
html
file type The format of a given file. For example, graphics files are often saved in
GIF format, while a text file is usually saved as ASCII text format. File types are
usually identified by the file extension (for example, .GIF or .HTML).
filter A constraint applied to a directory query that restricts the information
returned.
filtered role Allows you to assign entries to the role depending upon the
attribute contained by each entry. You do this by specifying an LDAP filter. Entries
that match the filter are said to possess the role.
