I have an existing database with a users table, and we are planning to take the database and use it for a new system built in ASP.NET MVC. However, what I am uncertain about is whether or not I am able to create a login system that doesn't use the built in account controller or a regular membership provider so that we can still use the existing table structure.
So my question is, would this be possible? Or even particularly difficult to do if it is?
What is the most widely accepted way of doing things and the simplest?
