[SunHELP] SUMMARY: ssh2 key auth

much thanks to Larry Snyder and Ben Ricker for assistance.  Hopefully
someone else can benefit as this is confusing as hell if you are new
to it.

my troubles were with the "identification" and "authorization" files
as they are parsed by ssh and must contain valid keywords and reference
the actual key filenames. 

SSH2 v3.1
**** CLIENT MACHINE ****

I ran ssh-keygen2 (null pass phrase) which created

Private key saved to /opt/home/luser/.ssh2/id_dsa_1024_a
Public key saved to /opt/home/luser/.ssh2/id_dsa_1024_a.pub

then:
cd /opt/home/luser/.ssh2
echo "IdKey id_dsa_1024_a" > identification
then ftp'd id_dsa_1024_a.pub to the server, same dir, its recommended
  that you delete the pub key off the client

**** SERVER MACHINE ****
cd /opt/home/luser/.ssh2
echo "Key id_dsa_1024_a.pub" > authorization

I modified /etc/ssh2/sshd2_config uncommenting AllowedAuthentications

## Authentication
## Hostbased and PAM are not enabled by default.

#       HostbasedAuthForceClientHostnameDNSMatch no
#       SshPAMClientPath                ssh-pam-client

and restarted /etc/init.d/sshd2
