Question on Apple DEP Rollout with Afaria 7

Hello

I have a question on Apple DEP Rollout. We testing the DEP Rollout with Afaria 7 SP7.

In rollout process the user is prompted for a username and password (AD Credentials for Authentication). On this Screen we see a HTML Code. so i think this side will transmit from Afaria.

Does anyone have an idea which HTML Page  is transmitted by Afaria and how these can be adapted?

Regards

Gianni
