Why does sshd on fedora 5 reject public key exchange



Hi
Thanks in advance for any help

I am accessing a fedora 5 machine using public key authentication
but the authentication is rejected and a password is requested

I am currently using the default configuration for /etc/ssh/sshd_config

I have found this to work in the past.

Does anyone know what the problem is here. When I try and access the machine
using ssh in verbose mode I get the following output

$ ssh -v mike@xxxxxxxxxxxxxx
