[Planetlab-devel] Inconsistencies in records

[Jeannie Albrecht]

As an aside, the fact that Danny can't authenticate with his private
key is a little strange.  I have verified that he is using the correct
keys (public and private), and he is able to use these keys to login
to PlanetLab nodes.  However sfi keeps reporting a key mismatch error.
 Is it possible that the database that we connect to via sfi is not
entirely in sync with the information we see when we log in to PLC
through the website?  That would explain some of our current issues...

Thanks,
Jeannie
