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
www.[yourdomain].[domain]
might point to a real machine called
realthing.[yourdomain].[domain]
where the server currently exists.
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.
gateway See Directory Server Gateway (DSGW).
general access When granted, indicates that all authenticated users can access
directory information.
