How to verified .mobileconfig file?

I am having this same problem.. have you resolved it?

You have to sign the profile with a valid SSL Cert and Key (which you have to buy from a SSL Cert Authority)

I cannot find any documentation on this, can we purchase ANY SSL certificate or is there a specific can that needs to be used? Does anyone have a detailed proceedure for signing the profile (I think you need the full certificate chain, for example). A link to documentation would be great as I am just not finding it.

MAINTAINING CERTIFICATES

The easiest way to get that nice green "Verified" text you're after is to install and automatically trust on the target devices the self-signed certificate you use to sign the profiles in Configurator.

First create an identity in the Preferences of configurator. This will put a new self-signed certificate into your keychain.

Next, open up your keychain, find the certificate, and export it on your desktop.

Then head back to configurator and create an additional payload under "Certificates", import the certificate you just exported, and don't forget to fill up the password field with the password you set when you exported the certificate from the keychain. I would suggest to create a separated profile containing just this certificate payload.

Finally, install this profile on the target device. The certificate will be added to the device's keychain and automatically set as Trusted. From then on, every profile created in Configurator with this identity will show as Verified on devices with this certificate profile installed.
