Single Signon Implementation in ASP.NET ( Different Domains with two different applications )
<p>we have a production site like www.Domain1.com, and developing a new web application  www.domain2.com, and would like to implement single sign on. </p>

<p>I am looking for solution pretty much like how google works like login to gmail, in gmail navigate to other google apps or we can open new window and we can use picasa or other google apps with out login.</p>

<p>I have found an interesting solution, where we will be developing a dedicated Authentication site like www.sso.com.</p>

<p><a href="http://www.codeproject.com/KB/aspnet/CrossDomainSSOExample.aspx" rel="nofollow">http://www.codeproject.com/KB/aspnet/CrossDomainSSOExample.aspx</a></p>

<p>we use webfarm environment, site 1 and site 2 will be deployed in webfarm environment, but when we deploy www.sso.com in webfarm , this solution will not work.</p>

<p>I am sure google might have implemented www.sso.com service in webfarm environment. i am trying to understand and implement the same.</p>

<p>Experts i kindly request your help in this direction , any information which helps me.</p>
