Maps the external security user names to Actuate security user names. Either use GetTranslatedUserNames in conjunction with the external registration security level, or use the same user names for the external and Actuate users.

For example, a user with the Actuate Administrator privilege can manage all items in an Encyclopedia volume. If the Administrator user in the external security system has a different meaning, GetTranslatedUserNames can map the external security user to an Actuate user with a different name.
