13.1 Authentication
The ETH-100 requires valid user authentication when configuration or point
information is modified via the web server. The authentication request will
appear as a browser popup box that will request entry of a user name and
password. The unit contains two different security realms: an administrator
realm and a user realm. Each of these realms has a different username and
password, and applies to different configuration items. This division of
authentication realms allows a device administrator to retain control of critical
configuration items (such as a unit’s IP address and point definitions) while
allowing a device user with appropriate authorization to change point values
(i.e. control and configure the attached drives). Refer to Figure 19 for a screen
shot of the administrator realm authentication dialog box, and Table 4 for initial
factory-set authentication values. Note that the username and password are
case-sensitive, and that once authenticated, the authentication will remain in
effect from that point until all browser windows are closed.

Note
that there is a known issue with Internet Explorer in regard to Network
Authentication: on occasion, IE may not allow a user to Authenticate, even if a
valid username and password are entered. This problem only occurs when a
user attempts to authenticate for both the USER and ADMIN realms in the
same IE session. To resolve this issue, simply close all web browser windows
and restart Internet Explorer.
