Alias Attribute Use Case

This use case shows two LDAP user directories, which identify the last name of users, but the directories have different underlying schema.

Note: Review the advanced user attribute mapping examples, which detail how to use different attribute mapping types to identify the same user attribute across different directory types.

The following illustration details how two alias attribute mappings can create a common view of the same user information.

1. Two user directories identify the last name of users differently:
   • Directory A identifies the last name of users with sn.
   • Directory B identifies the last name of users with lastname.

   This results in two different views of the same user information.

2. LastName is the common name or alias that is mapped to the underlying directory schema:
   • LastName is mapped to sn in Directory A.
   • LastName is mapped to lastname in Directory B.

LastName results in a common view of the same user information. Use LastName when defining assertion attributes or NameID attributes that use the last names. The system has no concern for the directory-specific schema because the directories are operationally identical.
