Authentication Description
Kerberos
(see Figure B-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.
