Dynamic Provider Settings Not Refreshing Until IIS Pool Recycle

[KhandelwalMayur28]

Which version of Duende IdentityServer are you using?
7.0.8

Which version of .NET are you using?
8

Describe the bug
The dynamic provider did not refresh its settings. I accidentally entered the wrong setting in the database, and even after correcting it, the changes didn’t reflect until the IIS pool was recycled.

A clear and concise description of what the bug is.

To Reproduce

Steps to reproduce the behavior.

1. Store provider settings with some incorrect data in the DB
2. Try to login with this provider, so it gives the error (For example - Authority Url has some misspelled.)
3. Correct data in DB

I’m still unable to log in, even though the GetBySchemeAsync method returns the correct data. The same error persists until I recycle or restart the IIS pool.

Expected behavior

It should work without the need to recycle or restart the IIS pool. Is there something I’m overlooking?

This sounds like the dynamic providers may be cached (see docs). Can you double check your caching configuration?

If you have caching enabled, you can set the cache timeout in the IdentityServer options:

builder.Services.AddIdentityServer(options => {
    // ...
    options.Caching.IdentityProviderCacheDuration = TimeSpan.FromMinutes(1); // 1 min cache instead of the default 1 hour
    // ...
})
    // ...
