Currently we have got one web server on which all the applications resides.
We are thinking to shift some of our applications onto other server so may be first server will be called server1.domain.com and the second one will be called server2.domain.com.
What i want to do is if the user logsd in on server1 and then if he clicks on some link that takes him to the second server, then he should not be asked to login again as the user was already authenticated on the first server and vice-versa if he logins first from second server and goes onto first server.
How do i achieve the above.
Our website is in asp.net and sql server 2008 r2 with the 2008 r2 operating system.
