Network Address Translation (NAT) - Allows a single real
IP address to be used by multiple PCs or servers. This is
accomplished via a creative translation of inside “fake” IP
addresses into outside real IP addresses.
open setting - A setting assigned to a service port or library
category when creating a rule, or when setting up a filtering
profile or the minimum filtering level. If an item is given an
open (pass) setting, users will have access to it.
organizational unit (ou) - An attribute type that can be
entered in the LDAP Distinguished Name for a user group.
override account - An account created by the global group
administrator or the group administrator to give an autho-
rized user the ability to access Internet content blocked at
the global level or the group level.
PDC - A Primary Domain Controller functions as the authen-
tication server on a Windows NT domain. This server main-
tains the master copy of the directory database used for vali-
dating users.
profile string - The string of characters that define a
filtering profile. A profile string can consist of the following
components: category codes, service port numbers, and
redirect URL.
protocol - A type of format for transmitting data between
two devices. LDAP and SMB are types of authentication
method protocols.
proxy server - An appliance or software that accesses the
Internet for the user’s client PC. When a client PC submits a

from the Internet and sends it to the client. A proxy server

caching for bandwidth and performance reasons.
