Authentication Description
Kerberos
(see
Figure 6-4 )
Kerberos is a different form of 128-bit data security. An adapter is required to have its
request for access point resources authenticated with a Kerberos server before the server
permits the access point to transmit and receive data with the associated adapter. When
Kerberos is selected, the KDC and Realm entry fields appear. The KDC field should remain
with the default KDC name (krbtgt) unless it is changed in the server. Enter the name of the
server that hosts the Kerberos KDC in the Realm field. The KDC is located on a server and
maintains information about the access points and users it supports. The KDC also permits
the transmission and receipt of data once the credentials of the user are verified.
Tap Kerberos Options to configure different caching modes for Kerberos credentials.
When connecting to a Kerberos supported profile, the system can prompt for the
associated user name and password at specified instances during the authentication
process. Caching of credentials is optional.
Kerberos Options:
Select any combination of the following Kerberos Credential Caching settings:
Reset: When selected, the system prompts the user for the username and password
upon a warm boot.
Connect: When selected, the system prompts the user for login information when the
system initiates a connection to the ESSID.
Time: When selected, the system requests a user name and password after the specified
time parameter. Available time parameters are specified as an Interval (in minutes) or At
(hh:mm) a specified time (chosen with the pull-down menu). If a time option is not
selected, authentication continues without a user name and password verification.
Resume: When enabled, the system prompts the user for username and password after the
system is suspended and subsequently resumed. If disabled, the system prompts for a
username and password only if the user's credentials are not in the registry.
