unexpected behaviour in OpenSSH_3.7.1

[Wendy Palm]

we tried using links to the keys as well and it failed.
i didn't get into the code to see why, i just know that
when we took out the links and copied the files instead,
it worked fine for our particular configuration.
take that part out of the equation and see where you
are then.
