Log On/Off Application
When the user launches the
Log On/Off
application, the vehicle computer may be in two states; the user may
be logged onto the vehicle computer by already entering credentials through the login box, or there are no user
logged on. Each of these states have a separate set of use cases and a different look to the dialog box.
User Already Logged In
If already logged into the vehicle computer, the user can launch the login dialog box for the following reasons:
•
Connect to and re-enable a cancelled profile. To do this:
- Launch the password dialog.
-
Select the cancelled profile from the profile list.
- Login to the profile.
•
Log off the vehicle computer to prevent another user from accessing the current users network
privileges.
•
Switch vehicle computer users to quickly logoff the vehicle computer and allow another user to log into
the vehicle computer.
No User Logged In
If no user is logged into the vehicle computer, launch the login dialog box and log in to access user profiles.
The
Login
dialog box varies if it is:
•
Launched by Wireless Application, because the service is connecting to a new profile that needs
credentials.
•
Launched by Wireless Application, because the service is trying to verify the credentials due to credential
caching rules.
•
Launched by a user, when a user is logged in.
•
Launched by a user, when no user is logged in.
Device Username Field
The device username is a high level username used to link different network credentials to the same person as
explained above. The Device Username field is only writable when there is no user logged on. Otherwise it is
static text. The Device Username has a maximum length defined in the WCSAPI.
NOTE
Re-enable cancelled profiles using the Profile Editor Wizard and choosing to connect to the cancelled
profile. Cancelled profiles are also re-enabled when a new user logs on.
