We have implemented SSO based on cookies.
1. user clicks the help link in our app (www.app1.com) , cookie set up done (respose.addCookie)
2. request will redirect to www.help.com(third party software, cant change anything)
3..Here if the SSO enabled, it will redirect to the another URL (www.issues.app1.com) .
4,Have to get the cookie(User details) set in #1 here and validate.
Its working fine .But if we change the www.app1.com to www.abc.com , SSO is not working. We cant change www.help.com and www.issues.app1.com.
How to share the cookie in cross domain across 3 apps ? because middle app , we dont have control over it.
Urgent issues.Please help.
