Description

Hello!

I have an injected mode FunctionApp hosting DfMon. Currently it's using in-process mode (DurableFunctionsMonitor.DotNetBackend v6.7.1) and I have gotten server-directed login flow working, in accordance with the documentation.

Then, I tried switching to DfMon Isolated (DurableFunctionsMonitor.DotNetIsolated v6.7.3), but then the authentication breaks (401). Are there any differences in authentication configuration between in-process and isolated? How about the redirect URL? Should it still be this for isolated:
https://<my-dfm-function-app-name>.azurewebsites.net/.auth/login/aad/callback

Any help with troubleshooting appreciated!

Research direction

Start with the linked authentication documentation and compare the in-process configuration with the isolated setup described in the issue. Reproduce the 401 and verify whether the /.auth/login/aad/callback redirect URL and server-directed login flow behave differently; done means isolated mode authenticates successfully.
