Hi, Can anyone help me on this one.
What are the security risks of switching of kerberos pre authentication?
The reason for this question is that our VPN3000 concentrator does not
support pre authentication.
However before we go switch off pre auth i would like to get your view on
the risks, if any?

Thanks
