Blazor Server Application - Integrated SAML2

hydeinthesky 11

Good Day Everyone

at our company we have a SSO provider which is in SAML2, we have integrated this on ASP.NET Webforms and ASP.NET MVC 5 projects, but we haven't tried to integrate it on Blazor Server Application as we are starting to develop our first Blazor Application. I saw a tutorial for a basic Login page for Blazor, but for external authentication, there is facebook, google etc. but I can't find a sample for SAML2.

Does anyone here has successfully integrated SAML2 to there Blazor Server Application? if yes can you teach me how, if you have also successfully integrated SAML2 to your Blazor Web Assembly application, it will be good to share it also here.

Thanks and regards.

You have two options.

the first is to use cookie authentication and have the hosting page do the authentication. The hosting page when thane render login information to a JavaScript object loaded by a custom authentication provider, or pre-render could use pre-render persist state to set the data loaded by the provider.

the second is to use msal in the blazor WASM app.

The issue with microsoft library is that it is not extensive to customization for better user experience.

I had to go for a third-party solution to achieve much needed customization.

Thanks for the answers, I explain to you the concrete case:

We have a Blazor-ASP.NET Core Hosted application on .Net Core 6.

In an on-premise IIS for a client where they authenticate against their locally corporate Active Directory.

Now we proceed to migrate to the Cloud, logically we no longer have access to the client's local active directory and we need to maintain that type of authentication.

Azure Ad B2C has been ruled out since the client does not have it or want it, so we need to implement some SSO authentication mechanism with SAML2 in the application with some identity provider that the client has so that they can continue authenticating in the same way.

I can't find official documentation about it or examples on the internet to configure Server and Client(Wasm) applications with this method.

Is it feasible to do it?

If not, what would be the alternatives?
