[FreeNX-kNX] cannot ssh as nx-user

[Clay McCoy]

I must be overlooking something.  I was able to ssh as nx-user a few 
days ago before I reinstalled with new rpms.  Now, no matter what I do, 
I get prompted for a password.  I have read, checked, and rechecked 
everything here:

and here:
http://fedoranews.org/contributors/rick_stout/ssh/

I am positive that I have the correct client key in the right place with 
the right permissions.  Isn't that basically all that matters?  I have 
followed all the advice on these two pages exactly.  I still get 
prompted for a password.  What now?
