get some invalid value in User-Name attribute

I get something like 'aolnet/aol.dsl.newuser.10A50001000300010001US92C1.0000.prod' in User-Name attribute . I think it should be connect-info attribute !!!!! and In this case all %{connect-info} is empty (not null) . i increase the connect-info to 150 character but nothing happens. I am confuse in this case .... what is the problem? it seams that some attribute is swap !!!!
