That's great info -- thanks.  I will start following that bug report 
with great interest.

I can see where the issue is and how this could be a serious problem.  
It will be good to see how it is fixed.

One suggestion that I'll make both  here and over there (I don't know if 
you have any pull on this), is that this "feature" is documented in the 
4.0 man pages.  In smb.conf(5) it says:

"Also note that the apparent service name will be changed to equal that 
of the requested service, this is very useful as it allows you to use 
macros like %S to make a wildcard service."

I'd like to see the feature available again (maybe with an understanding 
of risk that it can entail), but if not then that description should 
probably be struck from the documentation.

Thanks for the spot-on tip of where the bug is and the issues 
surrounding it!
