Specifications

If a user uses the browser to connect to web servers that support NTLM using a work Wi-Fi network or a work VPN network,
the tablet supports NTLMv1 authentication. The tablet also supports the message-signing capabilities of both NTLMv1
standard session security and NTLM Extended Session Security (also known as NTLM2). The web servers can be located
either inside or outside of your organization's environment.
How work apps are installed on a
BlackBerry PlayBook tablet
If you configure required and optional apps for BlackBerry PlayBook tablets using the BlackBerry Device Service, the
BlackBerry Device Service adds the apps to a shared network folder for apps that you specified. If you configure an app
that is publicly available in the BlackBerry World storefront as an optional app, it is not added to the shared network folder
for apps.
Apps that you specify as required are installed on the tablet. Users can install apps that you specify as optional from the
Work tab of BlackBerry World on the tablet. The optional apps that are in the shared network folder are sent to the tablets
from your organization's network. They are not uploaded to the BlackBerry World servers and are not available to users who
are outside of your organization.
For more information, see the BlackBerry Device Service Advanced Administration Guide.

When a BlackBerry PlayBook tablet prevents a user
from accessing work data or apps
You can use the BlackBerry Device Service to allow a user to access work data and work apps on a BlackBerry PlayBook
tablet. A tablet does not permit the user to access work data or work apps when you or the user deletes all tablet data.
If you configure the "Password Required for Work Space" IT policy rule to enforce the use of a password for the work space
and the user types the password for the work space incorrectly more than the "Maximum Password Attempts" IT policy
rule permits, the tablet closes all work apps and deletes the work space.
Personal data and personal apps are not affected by the actions that the tablet performs to prevent the user from
accessing work data and work apps.
