Description

As an admin, I want to know who the current user is so that I can have traceability into logging (#9 ) and see only my chats (#5 )

Expected/desired behavior

Please include any acceptance criteria here (should look like tasks to complete for the issue to be resolved)

• [x] I can get the AAD guid for the signed in user from Azure Active Directory.

• If the user is already logged into the webapp and the auth header is available, use that.

• Give me a way to do local dev.

• The login should NOT be the app service managed identity, but the user.

• If the user is not already logged into the webapp, redirect to login screen.

Mention any other details that might be useful

This may be a prereq for #5 and #9

AAD integration is in there, but want to make sure that cascades to cosmos partitions, etc...

Added utils for auth that can be used on the front end or the backend.

• frontend/src/auth/authUtils.tsx
• backend/auth/auth_utils.py (from auth.auth_utils import get_authenticated_user_details)
