This article provides information about the working behavior of Android devices, when the Require passcode on device feature is enabled on MSG.
When the Require passcode on device feature is enabled on the MSG, the passcode setting on the device is not mandatory.
Even after enabling the Require passcode on device feature on MSG, Junos pulse works normally, with or without setting the passcode on Android devices.
When profile is pushed, with the Require passcode on device feature being enabled, there should be a notification to set the passcode on the device; until the passcode is set, the notification should not disappear. Junos pulse should work, with or without the passcode being set on the device. When the passode is set, the notification should go away.
