Single-sign-on in Extjs 4

How can we implement Single-sign-on in Extjs4 where there are two different开发者_JAVA百科 domains

1. domain1.com
2. domain2.com.

There are many approaches to Single Sign-On, but it is unlikely that Ext can help you with them. Since the final authentication takes place on the server, your SSO solution needs to focus on how the two servers can confirm the identity of the client.

Here are a few stackoverflow questions

• Here someone suggests OpenID
• If you are using Tomcat, there is a Tomcat feature that may help
• Here someone discusses SSO with LDAP

Anyway the bottom line is (as pef commented) you shouldn't be looking for an Ext SSO solution, you should look at what you're doing on the server and think about SSO from that viewpoint.
