Lenovo ThinkPad Deployment Manual page 18

A configuration file received by the ThinkPad Tablet must have a specific file extension (.lenovoconfig).
The Lenovo Profile Manager is registered as the handler for files with this extension. When a file with this
extension is received on the device and tapped by the user, the XML Configuration Profile Handler will run.
The Lenovo Profile Manager calls into the Lenovo Device Policy Manager Service to perform an initial
parse of the contents of the file. The initial parse:
• Verifies that the XML file contents are valid against the schema
• Determines what settings are included in the file
The Lenovo Profile Manager is registered as an Android Device Administration Receiver using the native
Android capabilities.
The Lenovo Profile Manager also displays information about the installed profiles to the user. When the user
touches Settings->Location & security->Configuration profiles, a list of installed profiles will be displayed
using the "DisplayName" property of the configuration file. If no profiles are installed, the application will
display the message "No configuration profiles have been applied." If multiple profiles are installed, the user
will see a list of them. The device will show which policy is the applied policy at the bottom of the page.
If the user selects an installed profile from the list, the details of the configuration settings in that list will be
displayed. All installed profiles are displayed by the Configuration Profile Handler. This allows the user to
view all configuration settings that have been applied.
The profile display also allows the user to remove selected profiles. Only configuration profiles that were
installed by the Lenovo Profile Manager can be removed by the user, as long as you did not set the property
indicating that the policy cannot be removed. Configuration settings that were not set by the Lenovo Profile
Manager will be displayed, but cannot be removed by the user.
The Lenovo Profile Manager also calls into the Lenovo Device Policy Manager Service to receive a list of
installed profiles, and receives the list of installed profiles, their source, and whether the profile is allowed to
be installed from the Lenovo Device Policy Manager Service.
