Starting clean after rebuilding ipa2 and desktop2 and a gdm login to
ipa2 as dean, if I "ssh dean at desktop2" it will consistently fail as
noted in my last note.  However, if I:

     1. su -
     2. ssh dean at desktop2
     3. logout of dean at desktop2
     4. logout of root at ipa2

then "ssh dean at desktop2" succeeds!

Does that answer your question?  So I do not think there is a race.  It
is more like the super user session leaves something behind that was
missing?
