Preferences - Lock Keyboard(Section)__Allow keyboard locking
Enable keyboard locking via star-key or timeout. On OCS servers this setting is turned on if the inband provisioning parameter ucEnforcePinLock has a value of "true". If its value is "false" this setting is left unchanged (i.e. it may be turned on or off at the user's discretion). Note that even when this setting is turned off, the user can still lock/unlock the phone via the web interface directly by changing the phone's lock state (see keyboard_lock).
