We have a pre-existing website (e.g. www.mysite.com.) sitting on server ProdWeb1. It is using their own custom authentication forms based authentication database ProdDB1.

We plan to get a new community site (e.g. www.mycommunity.com) going on a separate severProdWeb2.

  1. Community Site ( www.mycommunity.com)
    1. Customer login to  www.mycommunity.com . We will get the logged in user information e.g. email id, user id etc.
    2. User will be provided a link for the  web sitewww.mysite.com so that they can use their functionalities .
    3. Once user click on the  link  www.mysite.com, logged in user’s email id will be passed (in a way that it is not visible to the end user).
    4. www.mysite.com website get the email id, validate it in heat and authenticate the user without prompting for the authentication.

We can not store values in a cookies as both sites are in different domain. Any idea of how to implement SSO for the above scenario would be much appreciated.

Thanks,
