Jonathan,
Don't know whether you fixed this or not, but I've just got round to
reading this post.
The server is reporting the following to the client:
debug: server offers auth methods ''.
I would check the syntax of your AllowedAuthentications in your sshd2_config.
I'm not sure whether it's just a typo in your mail, but it should
begin with a capital "A":
AllowedAuthentications publickey
HTH,
Nathan

I am trying to setup sshd to run as a non-root user to limit connections
to and from certain hosts. I'm running ssh.com v3.2.9 on Solaris 9
on an e25k and I am able to start sshd as myself, but login using keys
doesn't work. I've got "allowedAuthentications" set to just "publickey"
since passwd won't work and authorization and identification files are
correct since I can login remotely using keys. Any one have any clues?
TIA.
The daemon tells me:
