ssh login delays 12 seconds

Hi,

Been hitting my head off for the past hour or so to resolve my ssh login lag of about 12 seconds to a centos server.
The fix can be done in the client if you are using putty by disabling GSAPI option:
   Connection/ssh/auth/GSAPI
   Attemp t GSAPI authentication (SSH-2 only)

To fix it permanently, then I believe that you will have to do it in the server. Let's try ...
I am using centos:

Did the following in /etc/ssh/sshd_config:
# GSSAPI options
GSSAPIAuthentication no
#GSSAPIAuthentication yes

It worked! Now, I have no 12 second delay!
