i have a requirement to authenticate share point from an asp.net application, if an user is authenticated to asp.net and after that also he able to authenticate to share point application .
in asp.net application there is one link viewbidata , if user click this page he should redirect to share point and view bi pointers.
how i accomplish this scenario, here asp.net is farm based authentication enable, and it has users in sqlserver and authenticate from sql server.
sharepoint web application is claims based authentication .
Here how i write a custom Security token service and it must use asp.net application or rely on asp.net application authenticated users to authenticate sharepoint.
i want to authenticate sharepoint claims enable web application from an asp.net application which use farms based authentication.
I want to log in to a sharepoint site with the account or user its already authenticated in an asp.net application .
1) an user login to an asp.net application( which is enable farm based authentication ) and this user validate from sql server and login successfully
2) after login successfully this user can see a link in Home page, that redirects to share point site(which is enable claims based authentication and in different domain than asp.net application )
3) and in this step Here i want ,this user automatically login to share point site ,
but without asking any authenticate page or login page.
here how i achieve this scenario when i create a custom sts service,?
