Pre-Check Host name overlap with vRA properties in Active Directory

Hey ALL

I'm building the first BluePrints and it basic information. The Challenge I have starts very early. We have an existing Active Directory where manual and automated deployments meat each other. Means vRA and Ops Teams manage AD objects.

I can create host names according to our Corp naming convention using custom properties in vRA but I'm now looking for a way to let vRA check if the generated hostname exists already in active directory, created by an Operator and if it exists vRA shall just increase the next available sequence number.

Any ideas welcome

Many thanks up front

Rafael
