Identity Server 3 compatibility

[senj]

Hi,

I'm writing Services with Asp.Net Core but we still have an Identity Server 3.
Can I use Token Validation in Core with the Identity Server 3?

Thanks..

yes

I'm not able to use IdentityServer4.AccessTokenValidation against identity server 3 with reference token.

AccessTokenValidation v3 config :
app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions { Authority = "https://localhost:44333/core", RequiredScopes = new[] { "myScope" }, });

AccessTokenValidation v4 config :

app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions { Authority = "https://localhost:44333/core", ScopeName = "myScope", });

i get 401 and i'm not able to diagnose the problem, i've no clue what UseOAuth2IntrospectionAuthentication is :D

I could get the system working by using JWT token with Microsoft.AspNetCore.Authentication.JwtBearer thought

you need to specify a scope secret.

Unauthenticated token introspection is not supported anymore in idsrv4
