Question

Besides what it comes with in 2.0 (the generated aspnetdb.mdf), is there a standard login authorization authentication system for asp.net Internet websites? One that can plug into a website.

Answer 1

“the generated aspnetdb.mdf” is the ASP.NET Membership model. You can use it in websites without the generated aspnetdb.mdf.

From an article in MSDN called Introduction to Membership:

ASP.NET membership gives you a
built-in way to validate and store
user credentials. ASP.NET membership
therefore helps you manage user
authentication in your Web sites. You
can use ASP.NET membership with
ASP.NET Forms authentication or with
the ASP.NET login controls to create a
complete system for authenticating
users.
