Option 2 (recommended for production): An AAD admin can create the AAD applications for you. The deploy/scripts folder contains the aad-register.ps1 script to perform the AAD registration separately from the deployment. The output of the script is a file containing the relevant information to be used as part of deployment and must be passed to the deploy.ps1 script in the same folder using the -aadConfig argument.

cd deploy/scripts
./aad-register.ps1 -Name -ReplyUrl https://.azurewebsites.net/ -Output aad.json
./deploy.ps1 -aadConfig aad.json
