passphrase for non existent key?

[Robert Mooney]

Hi there.  I'm being asked for a passphrase for a key file that does not exist.

See debug output below.  Both client and server default to SSH2.  Creating a DSA key without a password and copying the public
portion to the server's authorized_keys2 allowed me to login w/o a password.  I downloaded and installed the latest version of SSH
from OpenBSD CVS, and now its asking me for the passphrase to a non-existent RSA key.  i.e. /home/rjmooney/.ssh/identity doesn't
exist on either end.  Nor does id_rsa.  Yet, I'm still being prompted.

IMO (and maybe this just a problem with the OpenBSD version), SSH should just skip keys that don't exist.
