Configuring Single-Sign On for SharePoint: Part 2

In the previous blog you learned how to setup and configure Single Sign-On (SSO) for SharePoint. In the SSO environment, the back-end or external data sources are referred to as “enterprise applications”. An enterprise application definition needs to be configured for each external data source that SharePoint will connect to. After you have started the SSO service, configured Central Administration, and created and encryption key, you must configure account information for the enterprise application definition.

1. Navigate to the Operations page of Central Administration.
2. In the Security Configuration section, click the Manage Settings for Single Sign-On link.
   
3. Click Manage Settings for Enterprise Application Definitions.
