So I have tried to implement OpenId Connect authentication in my ASP.NET Core 2.0 web api. Various articles or tutorials point to using AddJwtBearer (e.g. this article on octa).

In results I got error that looked like this:

Bearer was not authenticated. Failure message: No SecurityTokenValidator available for token:

In the end I somehow figured out that using AddJwtBearer was not correct solution and I had to use AddIdentityServerAuthentication because I got tokens from Identity Server.

I am writing this so that would help others trying to google this.
