Map a Sort Name Attribute with Expression and Alias Mapping Types

Use an expression attribute mapping and an alias attribute mapping to represent the sort name of a user in Directory A and Directory B.

Deployment

• Directory A does not uniquely identify a the sort name for each user. For each user, Directory A stores the first name as givenname and a last name as surname for each user.
• Directory B identifies a sort name using sort_name.

Solution

1. Create an expression attribute mapping for Directory A:

   Name

   SortName

   Mapping Type

   Expression

   Definition

   (surname + "," + givenname)
   

   Note: The expression must conform to the syntax rules of an expression.

2. Create an alias attribute mapping for Directory B:

   Name

   SortName

   Mapping Type

   Alias

   Definition

   sort_name

When referencing users in Directory A, the sort name is calculated based on the specified expression. When referencing users in Directory B, the sort name is represented by the attribute sort_name.
