Windows 7: Kerberos Authentication to UNIX from Windows 7 OS

Kerberos Authentication to UNIX from Windows 7 OS

Hi, I am testing Windows 7 OS in our domain and found that Kerberos authentication to UNIX domain from Windows 7 is not working. It is prompting for a password everytime I connect to a unix host and not going throuh pass-through authentication. This works perfectly fine on Windows XP OS in our environment.

Is there any setting that needs to be done to make this working from Windows 7 client?

Hi there could you try disabling User Account Control in Windows 7?
Control Panel\User Accounts and Family Safety\User Accounts\Change User Account Control Settings. Bring it all the way to the bottom.
