APPENDIX G GLOSSARY

directory service - Uses a directory on a server to auto- mate administrative tasks for storing and managing objects on a network (such as users, passwords, and network resources users can access). ADS, DNS, and NDS (Novell Directory Services) are types of directory services.

Distinguished Name (DN) - A string of “cn” and “dc” attribute types comprised of the username and group name, domain name, and DNS suffix. For example: “cn=admin_user, cn=admin, dc=yahoo, dc=com”. The “ou” attribute type also could be a part of the DN. For example: “cn=Joe Smith, ou=users, ou=sales, dc=acme, dc=com”.

DNS - Domain Name Service is a distributed Internet direc- tory service. DNS is used mostly for making translations between domain names and IP addresses.

domain - An entity on a network comprised of servers, workstations, and peripherals.

domain component (dc) - An attribute type entered for a domain name and DNS suffix when using LDAP.

domain controller - An authentication server that answers logon requests from workstations in a Windows NT domain. There are two types of domain controller servers: Primary Domain Controller (PDC) and Backup Domain Controller (BDC).

entry - A collection of attribute types that comprise a Distin- guished Name (DN). Each attribute type of the Distin- guished Name has a type and one or more values. These types are mnemonic strings, such as "cn" for common name, "dc" for domain component, or “ou” for organizational unit.

filter setting - A setting made for a service port. A service port with a filter setting uses filter settings created for library categories (block or open settings) to determine whether users should be denied or allowed access to that port.
