OSX 10.8.5 won't connect to Windows 2008 R2 NFS

Question

Hi
We have about 25 Mac clients in our Microsoft Windows environment. OSX is bound to our single Active Directory domain and all our Windows server are 2008 R2.
For several years we have been using SMB filesharing and connecting the Mac clients to our Windows file server. Now we are experiencing performance problems and are evaluating NFS file sharing on our file servers. The Mac client won't connect to our Windows NFS server and we have pinpointed the problem to OSX requesting Kerberos token encryption type "des3-hmac-sha1" which is unsupported by Windows.
How can we configure NFS / Kerberos on OSX 10.8.5 to use a different Kerberos encryption type ?
I have tried to update the /etc/krb5.conf file without success. OSX is still asking for the same encryption type.
The file /Library/Preferences/edu.mit.Kerberos does not exist. The my understanding OSX 10.8.5 uses the Heimdal Kerberos implementation.

So Does Maverick Fix this issue?
Im trying to sort out my inlaws wireless printing issues. They have a mac running 10.6.8 works fine wirelessly and USB. They have another mac running 10.8.5 and this mac will not see the printer directly. I can print via mac 1 using a shared connection. But if you deselect mac 1 sharing options then mac 2 cannot see the printer. I can print via usb and via the shared connection using mac 1. But not directly.... So if Bonjour is no good on 10.8.5 does the update to mavericks fix it?
Thanks
