Cross Domain Single Sign-On

External Website Bookmarks can be created for application offloading portals to achieve a single point of access for users. This allows users to automatically log in to application offloading portals after logging into the main portal.

To use Cross Domain Single Sign-on (SSO)

  1. Create two or more portals with the same shared domain (from Virtual Host Domain name) and that need authentication. One portal should be a regular portal. These portals are also in the same SMA appliance’s domain so that a user can log in to both with the same credentials.
  2. Log in to the portal and create a bookmark.
  3. Set the service to External Web Site.
  4. Enable Automatically log in for the bookmark that enables Cross Domain SSO for this bookmark.
  5. Specify a Host that is a portal with the same shared domain name.
  6. Save the bookmark and launch it. The new portal is logged in automatically without any credential.

The shared domain names do not need to be identical; a sub-domain also works. For example, one portal is a regular portal whose virtual host domain name is “www.example.com” and its shared domain name is “.example.com.” The other portal’s virtual host domain name is “intranet.eng.example.com” and the shared domain name is “.eng.example.com.” If a bookmark to xyz.eng.example.com is created in the www.example.com portal, Cross Domain SSO works because “.eng.example.com” is a sub-domain of “.example.com.”
