Access Control
An access control list (ACL) specifies the individual host systems that are allowed access to the device.
(Not all devices support ACL, and support is limited to IPv4 networks.) By default, hosts with HTTP
connections, such as the HP Embedded Web Server (EWS) and IPP, can typically access the device
regardless of the access control list. To disable HTTP host access, clear the Allow Web Access check
box. Specify host systems by their IPv4 address or network number. If the network contains subnets,
use the address mask to identify whether the IP address designates an individual host or group of
hosts. You can enter up to nine host systems.
Windows
Windows authentication validates users in a Windows Domain. When enabled, users at the device
must provide valid credentials (user name, password, and realm). Authentication consists of verifying
the user's credentials with the key distribution center (KDC) and then searching for the user's e-mail
address and name by accessing the LDAP server.
Select the check box to assess the Windows authentication setting on the device, and then select
whether to enable or disable it. If enabled, provide the Windows domain, server, and port, and then
whether to enable reverse DNS lookup.
Note: On some older devices, Windows authentication cannot be disabled.
