722 Part VIII: Securing SharePoint <strong>Products</strong> <strong>and</strong> <strong>Technologies</strong><br />

Summary<br />

SharePoint Portal Server 2003 provides single sign-on functionality implemented by<br />

<strong>Microsoft</strong> Single Sign-On service. The SSOSrv service provides storage <strong>and</strong> mapping of<br />

credentials such as account names <strong>and</strong> passwords so that portal site–based applications<br />

can retrieve information from third-party enterprise applications such as ERP <strong>and</strong><br />

CRM systems. The credentials are encrypted <strong>and</strong> stored in the SQL Server database.<br />

For each enterprise application, you need to configure the corresponding single signon<br />

application definition. SharePoint Portal Server 2003 provides a programming interface<br />

to use the single sign-on feature. After you have configured the application definition,<br />

you need to create a Web Part that programmatically implements the single<br />

sign-on functionality using classes provided by SharePoint Portal Server, <strong>and</strong> then<br />

retrieves the data from the corresponding back-end application. There are numerous<br />

uses for single sign-on functionality in the enterprise environment.
