14: User Authentication 2. Enter the following: Enable Kerberos Check box displays as checked if this method is enabled on the User Authentication page. If you want to set up this authentication method but not enable it immediately, clear the checkbox. Note: You can enable Kerberos here or on the first User Authentication page. If you enable Kerberos here, it automatically displays at the end of the order of precedence on the User Authentication page. Realm Enter the name of the logical network served by a single Kerberos database and a set of Key Distribution Centers. Usually, realm names are all uppercase letters to differentiate the realm from the Internet domain. Realm is similar in concept to an NT domain. KDC A key distribution center (KDC) is a server that issues Kerberos tickets. A ticket is a temporary set of electronic credentials that verify the identity of a client for a particular service. Enter the KDC in the fully qualified domain format (FQDN). An example is emg.local. KDC IP Address Enter the IPv4 or IPv6 address of the Key Distribution Center (KDC). KDC Port Port on the KDC listening for requests. Enter an integer with a maximum value of 65535. The default is 88. Use LDAP Indicate whether Kerberos should rely on LDAP to look up user IDs and Group IDs. This setting is disabled by default. Note: Make sure to configure LDAP if you select this option. Custom Menu If custom menus have been created, you can assign a default custom menu to RADIUS users. Escape Sequence A single character or a two-character sequence that causes the EMG to leave direct (interactive) mode. (To leave listen mode, press any key.) A suggested value is Esc+A (escape key, then uppercase "A" performed quickly but not simultaneously). You would specify this value as \x1bA, which is hexadecimal (\x) character 27 (1B) followed by an A. This setting allows the user to terminate the connect direct command on the command line interface when the endpoint of the command is deviceport, tcp, or udp. See Key Sequences on page 235 for notes on key sequence precedence and behavior. Break Sequence A series of 1-10 characters users can enter on the command line interface to send a break signal to the external device. A suggested value is Esc+B (escape key, then uppercase "B" performed quickly but not simultaneously). You would specify this value as \x1bB, which is hexadecimal (\x) character 27 (1B) followed by a B. Enable for Dial-back Select to grant a user dial-back access. Users with dial-back access can dial into the EMG and enter their login and password. Once the EMG unit authenticates them, the modem hangs up and dials them back. Disabled by default. Dial-back Number The phone number the modem dials back on depends on this setting for the device port. The user is either dialed back on a fixed number, or on a number that is associated with the user's login (specified here). Data Ports The ports users are able to monitor and interact with using the connect direct command. U1 denotes the USB port on the front of the EMG unit. Listen Port The ports users are able to monitor using the connect listen command. Clear Port Buffers The ports whose port buffer users may clear using the set locallog clear command.
