i have a website with claim based authentication and i'm trying to do that, can anyone help me

Answer 1

What you are looking for is possible but will require quite some work and deep knowledge about kerberos.

Reverse proxy solutions like Microsoft TMG are doing what you would like to do. It is possible to implement "some kind" of reverse proxy that will take the username and password from an ASPX page, store the data in "some" place and use the reverse proxy (Microsoft Application Request Routing) functions to fetch the authentication information and integrate them into the proxied request. This is a really bad solution.

If your portal is running on Kerberos Authentication (in a classic oder claims mode web app) and you are able to get all needed security configurations you can use the S4U services and do a protocol transition from plain text username and password to a real kerberos token. This will only work in intranet single domain environments. More details:

The best solution if you don't what traditional asp.net membership FBA of sharepoint you can switch to ADFS and use IDP login page:

This will not excactly cover your requirments to stay on the SharePoint url but this is the simplest and cleanest way.

Look at this post. It describes how to resolve your problem.

Answer 3

Your question describes what is more commonly called Forms Based Authentication or FBA. Ironically, the page @Alexander links to has on it a link to a page about how to make a custom FBA login page for Windows Authentication.
