In the meantime I did more tests. The user requesting the FUD info does 
not have to be local to get a response, it just has to have a login name 
which is shorter than 20 chars (including local part, '@' and the domain 
name). If the login name is 20 chars or longer, the request times out. 
This is reproducible and definitely looks like a bug, or at least an 
inappropriate limitation. However, I am not much of a programmer to 
delve into the code to find it. Can anyone help?
