Service Provider may be installed in environments in which users have accounts on multiple resources. The account linking feature of Service Provider enables you to assign existing resource accounts to Service Provider users in an incremental fashion. The account linking process is controlled by the Service Provider linking policy, which defines a link correlation rule, a link confirmation rule, and a link verification option.
In the Administrator interface, click Resources in the menu bar.
Select the desired resource.
Select Edit Service Provider Linking Policy from the Resources Action menu.
Select a link correlation rule. This rule searches for accounts on the resource that the user may own.
Select a link confirmation rule. This rule eliminates any resource accounts from the list of potential accounts that the link correlation rule selects.
If the link correlation rule selects no more than one account, then the link confirmation rule is not required.
Select Link verification required to link the target resource account to the Service Provider user.
