The question is: Do you want to do client certificate authentication? If 
not then you should be able to disable client auth in the directory 
server and this message should go away. I'm not a FDS developer so I 
can't really say how one would do this configuration.

As for the trust issue, this goes a bit beyond my knowledge. This would 
be a good question for the NSS guys in the 
netscape.public.mozilla.crypto newsgroup (on nntp://news.mozilla.org).
