badge over asl.auth

In SB1 Programmer's Guide it is mentioned that "When using Shell authentication, the following properties can be set: ... badge.". I tried to pass badge url to asl.auth data but it seems that SB ignores it. It takes name, title, apps and other fields, but not badge url. If I pass the same url in some application over asl.badge it successfully activates a new badge page. Is it supposed behaviour? Calling asl.badge after or before asl.auth in login page unfortunatelly also has no effect.
