OpenSSH client not prompting me for password

[Al Sparks]

I'm trying to use my ssh client to connect to a server.  By the way,
I'm able to connect using PuTTY on an XP machine.  

When I
    ssh v whatever
the error at the bottom includes this:
  Permission denied (publickey,gssapi-with-mic,password)	

In the configuration file, I have:
   #GSSAPIAuthentication yes
   GSSAPIAuthentication no
   #PreferredAuthentications keyboard-interactive,passwd,publickey
   PreferredAuthentications keyboard-interactive,passwd

The commented out portions is what I normally use for settings.

No matter what I do, I can't seem to change the behavior of my ssh
client where it prompts me for a password.

Is there compilation switch that comes with the stock OpenSSH on
CentOS?

This is driving me nuts.  I'm able to use that client if I have a
public key that matches my private one just fine.  But I can't get
that client to prompt for a password minus that.

I notice that the OpenSSH server I'm connecting to has
GSSAPIAuthentication on.

Nevertheless, If I'm able to connect with PuTTY, and get a password
prompt, I should be able to do it with my ssh client.

What do I need to change in my /etc/ssh/ssh_config (or actually
~/.ssh/config) to make this work?
