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 www.example.com). Machines
normally get the IP address for a hostname from 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 www.yourdomain.domain might point to a real machine
called realthing.yourdomain.domain where the server currently exists.
E
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.
F
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.
G
general access
When granted, indicates that all authenticated users can access directory information.
