Framework similar to Membership control in ASP.NET

Question

Hi,

I am curious to know that like we have different way for intersecting data (LINQ to SQL, Entity Framework, Enterprise Library, etc). Do we have alternatives for membership controls?

Editing to eloborate it more:

I mean to say that like to connect with the database we have various options like one can use Linq to SQL or Enterprise Library etc. depending upon the requirement. Similar example is of logging, one can use either Enterprise library or log4net. I just wanted to know if there is any framework or group of control which is similar to .net membership control. Means I can provide a full authentication system without using orthodox asp.net membership.
