I have just deployed an Azure Blockchain Workbench. It shows up in AD among "App registrations", but it doesn't show up among "Enterprise applications." Because of this, I can't assign admin role to any users and I'm stuck, can't use the workbench.
What should I do to make it appear among the "Enterprise applications"?
Which Active Directory tenant are you working under? If it is the Microsoft tenant, then you wouldn't be having Administrative rights. Thus you will not be able to assign admin roles to anyone. You will need to create a new AD tenant where you are the administrator. Hope this helps.
