Move to Azure RBAC based on groups

[SeanKilleen]

Currently, individuals are granted access to the application.

These users are also part of a security group.

I'd prefer to grant access to only the group and remove the individual access.

This is currently blocked due to trouble getting group-based access to work.

Created a stackoverflow question to describe the problem.
