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.
