Create an Expression Attribute Mapping

You can map a common name to an expression that references one or more user attribute names specified by the user directory's underlying schema. An expression attribute mapping's data type is string, number, or Boolean. You can use expression attribute mapping to read the result of an expression, but not to write a value to a user directory.

Note: User attribute mappings are directory-specific. To create a global object that is defined as an expression, create a named expression.

To create an expression attribute mapping

1. Navigate to the User Directory: Name pane.
2. Click Create on the Attribute Mapping List group box.

   The Create Attribute Mapping pane opens.

3. Verify that Create a new object is selected, and click OK.

   The Create Attribute Mapping: Name pane opens.

4. Type the common name and a description of the attribute mapping in the fields on the General group box.

   Note: Common names must conform to the same rules as user attribute names.

5. Select Expression on the Properties group box.

   Note: Selecting Expression activates the Edit button. Clicking Edit opens the Expression Editor. The expression must conform to the syntax rules of a SiteMinder expression.

6. Type the definition in the Definition box on the Properties group box.
   • Example:

     Name: SortName

     Definition: (surname + ',' + givenname)

     Description: The common name SortName is mapped to an expression that references the user attribute names surname and givenname.

7. (Optional) Select Disabled to disable this attribute mapping.
8. Click OK.

   The Create Attribute Mapping task is submitted for processing, and the new attribute mapping is added to the list on the Attribute Mapping List group box.
