Hi all;
I've added the Identity scaffold to my Blazor Server (version 7) app. Works great for registering users. But now I need to set up roles & claims and then apply policies to pages. Is there a library or example or something that provides all the pages needed to CRUD all this? Preferably as Blazor (razor) files. But if it's MVC that gets added to the existing Identity MVC files, that'll work too. ??? - thanks - dave
The libraries already exist. The RoleManager adds roles to the roles table as well a claims to roles. The UserManager adds roles or claims to a user. There are no out-of-the-box UIs (Razor Pages, MVC, or Blazor Server) that come with Visual Studio I'm aware of but building the UI is basic and depends on how your application works. I'm sure you can figure it out.
apply policies to pages
Policies are typically assigned using attributes. See Claims-based authorization in ASP.NET Core.

I'm sure if you looked around the internet you can find someone that created examples. But again, pretty basic stuff.
Hi Joe; We have two sets of claim checks we need to do. We are creating an app that manages volunteers and so there are individuals that will have Admin rights for a single state. So I have a claim(Admin, Colorado) and you have a claim(Admin, Arizona). So we need to do two things. For the admin page, restrict it to people with a claim of (Admin, *). So any claim where the key is Admin. But then we need to programmatically get the specific claim(s) for the user so we can allow them to CRUD on the admin page for the state(s) they are an admin of. thanks - dave
And, that's what the AspNetRoleClaims table can be used for. A role can have claims. Use the RoleManager to interface with the table(s). Or you can have a separate role and claim. It all depends on how you wish to design this application.
I was hoping there were already UI pages for this, like Identity has for all the authentication functionality. But unfortunately... no. As you said, the API is there and the pages aren't too much work to create. thanks - dave

currently the Identity scaffolding uses razor pages rather than a blazor app. the razor pages are built in to the package. you can override the pages:

Unfortunately that link does not discuss handling roles & claims at all. The Identity package is aware of roles & claims, but provides no UI to manage them.
this is left as an exercise for the user. you can google for samples, but scaffolding does not include pages for claims/role management..
Ok, thanks (I'd accept your comment as an answer if that was allowed).
