Hi,

I've build some farm solutions for Sharepoint 2013 application with Form based authentication. I would like to know, can i configure form based authentication and windows based authentication on single site collection?

How it will work?

Since IIS7, you can't use both Forms Authentication and Windows Authentication in the same application.

Mike Volodarsky posted a workaround for ASP.NET to allow different pages to use different authentication schemes:
IIS 7.0 Two-Level Authentication with Forms Authentication and Windows Authentication[^]

However, that's unlikely to work with SharePoint, and it doesn't sound like that's what you want to do anyway.

Not easily as windows auth operates at a lower level than forms auth and will prevent access to your code before forms auth does its work. There are hacky workarounds if you google "asp.net mix windows authentication and forms authentication" and they seem to work, but you're pretty much breaking the architectural rules of .net so it's not straightforward.

Just found a blog post for SharePoint 2010 which claims you can do it:
SharePoint 2010 mixed Authentication[^]

And this one suggests it's still possible in 2013:
SharePoint 2013 Custom Claims (FBA) based Mixed Mode Authentication - Part 1[^]
