My client is trying to install an ipad app using Apple Configurator 2. The ipads are unsupervised but configured to be on a private wifi (no internet access). This was required for security reasons.

Using the Apple Configurator, a setup profile was created that installs the ipa onto a set of ipads. However, when the user clicks on the app icon they are presented with the "Untrusted Enterprise Developer..." alert. In order to trust the ipa, he needs to reconfigure each ipad (500+ ipads) to connect to the internet and then go into the profile area to manually establish trust.

.

My question is, does Apple Configurator 2 support a way to automatically trust the app?

This article states that only an MDM can establish the trust automatically.

Does this mean in ios 9.x, apple configurator 2 can't automatically establish this trust?

We went through a similar problem, currently Apple has no way around this. The device MUST connect to the internet to verify the certificate before it will allow the enterprise app to be used. On top of that it isn't just a one time process. The trust is only established for a certain amount of time (Apple wasn't able to tell us what that exact time is) so if the devices don't connect to the internet after a while this issue will come up again and the app will be rendered useless until the device connects back to the internet. From by understanding the only way around this is to publish the app to the Apple App store and trust is inherited when the app is installed this way. In addition to this the MDM route will automatically establish 'trust' but the certificate still needs to be verified so you will have the same problem.
