This read-only RlAAAServiceType reports the actual service used for a recorded line-password login, with console terminal access represented as a don't-care value. An admin cares because it confirms which real access method was used for the session rather than just the configured key, useful when the configured service type is a wildcard. For example, an admin auditing line-password access would check this field to see the actual protocol a user connected with rather than relying only on the entry's configuration key.
