I think the problem is you have

> DEFAULT Ldap-Group == "schueler", Airespace-Wlan-Id != 4
> Auth-Type := Reject,
> Reply-Message = "Schueler: Wrong WLAN!!!",

But it should be

DEFAULT Ldap-Group == "schueler", Airespace-Wlan-Id != 4, Auth-Type := Reject
    Reply-Message = "Schueler: Wrong WLAN!!!"
