We are using ezpublish legacy system. Suppose we have two sites a.com and b.com. A user logs into a.com. Now if he visits b.com he will be automatically logged in.
a.com and b.com is on same ezpublish installation. We have seen the single sign on (SSO) system. But it requires user to visit a.com from b.com to get logged into b.com.
How can we avoid this visit to a.com from b.com to get the users logged into a.com?
