[Bug 84899] Re: SSH with GSSAPIAuthentication option on SSH servers are very slow

I run into this with Ubuntu lucid frequently when connecting to CentOS
systems. I have no local Kerberos configuration.

A good fix for me would be to have SSH check if kerberos is locally
configured before trying to do Kerberos authentication. However I have
no idea how feasible this approach is.

There is no file /etc/krb5.conf on my system, neither is the krb5-config
package installed.

Title:
  SSH with GSSAPIAuthentication option on SSH servers are very slow

Status in Portable OpenSSH:
  New
Status in “openssh” package in Ubuntu:
  Confirmed
Status in “openssh” package in Debian:
  New

Bug description:
  Binary package hint: openssh-client

  In Feisty Fawn I noticed a very slow ssh connection to some local servers, the prompt login takes 5/6 seconds to appear.
  I solved this problem putting the option "GSSAPIAuthentication no" instead "yes" in the /etc/ssh/ssh_config file.

  SSH Version is 4.3p2-7ubuntu1
