I have two suggestions and a couple comments for you.

1) comment out the line with AuthorizedKeysFile

    In comparing your sshd_config with one from a working f13 system I
noticed that I had that line commented out, when I uncommented I got a
failure similar to what you mentioned.

2) modify the AuthorizedKeysFile to match the line below (the %h
causes sshd to look in $HOME/.ssh)

AuthorizedKeysFile      %h/.ssh/authorized_keys

Both of the above worked for me, after I broke the system by
uncommenting the AutorizedKeysFile line.

Your log it lists port 39169, but the sshd_config you posted has Port
22 - I'm guessing what you posted as your sshd_config doesn't match
what was in place when the log messages occurred.

I never allow root login, it just seems like asking for big trouble.
I always set PermitRootLogin no and use sudo or su - as needed after
logging in as a normal user, which seems much safer.

Please post another message saying whether or not the
AuthorizedKeysFile change(s) worked for you.
