AADSTS50001: The application named was not found in the tenant named .

Today we lost some investigating why we couldn’t authenticate a WinForms app using ADAL to Azure AD.

Here is the code we were using:

And here is the exception we got:

AADSTS50001: The application named .onmicrosoft.com/sample">https://<resource>.onmicrosoft.com/sample was not found in the tenant named <tenant>.onmicrosoft.com.  This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant.  You might have sent your authentication request to the wrong tenant.

Trace ID: a1b52908-f2c8-4f9d-aabb-e0050ff9ca0c

Correlation ID: 9f0ec9de-2f32-47b2-9d25-11333b2bd1d6

Timestamp: 2016-08-26 10:22:17Z

If you see the error above, triple check your configuration values. Almost all the time this means you have a typo somewhere causing Azure not to find the correct information. In our situation we had a typo in the APP ID URI… Confused smile

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
