Figure 4-13 Prompt for Login at Dialog Box
If the vehicle computer does not have the credentials, you are prompted to enter a username and password. If
the vehicle computer has the credentials (previous entered via a login dialog box), it uses these credentials
unless the caching options require the vehicle computer to prompt for new credentials. If you entered the
credentials via the profile, the vehicle computer does not prompt for new credentials. Table 4-9 lists the caching
options.
Entering credentials applies these credentials to a particular profile. Logging out clears all cached credentials.
Editing a profile clears all cached credentials for that profile.
The following authentication types have credential caching:
•
EAP TLS
•
PEAP
•
LEAP
•
TTLS.
Selecting the
At Time
check box displays the
Time Cache Options
dialog box.
Table 4-9 Cache Options
Description
At Connect Select this option to prompt for credentials whenever the mobile computer tries to connect
to a new profile. Deselect this to use the cached credentials to authenticate. If the
credentials are not cached, you are prompted to enter credentials. This option only
applies when logged in.
On Resume Selecting this reauthenticates an authenticated user when a suspend/resume occurs.
Once reauthenticated, the user is prompted for credentials. If the user does not enter the
same credentials that were entered prior to the suspend/resume within three attempts, the
user is disconnected from the network. This option only applies when logged in.
At Time Select this option to perform a local verification on an authenticated user at a specified
time. The time can be an absolute time or a relative time from the authentication, and
should be in at least 5 minute intervals. Once the time has passed, the user is prompted
for credentials. If the user does not enter the correct credentials within three attempts, the
user is disconnected from the network. This option only applies when logged in.
