vmware-config.pl and mandriva kernel

One more time, I'm getting the famous:

What is the location of the directory of C header files that match your running kernel? /usr/src/linux/include
The path "/usr/src/linux/include" is a kernel header file directory, but it does not contain the file "linux/version.h" as expected. This can happen if the kernel has never been built, or if you have invoked the "make mrproper" command in your kernel directory. In any case, you may want to rebuild your kernel.

NFS v4 and KDC in Active Directory

One more day spent to use the internal KDC from AD with NFS v4, without success.

It seems that the "net" command from samba 3.0.22 add a SPN in uppercase, I fixed that but it isn't suffisant to be able to use the SPN.

More generally, is seems that adding some SPN in AD isn't successful, even for CIFS:

for i in $(klist -k -e |cut -f5 -d' ') ; do kinit -k $i 2>/dev/null || echo $i BAD; done

for i in $(klist -k -e |cut -f5 -d' ') ; do kinit -k $i 2>/dev/null && echo $i OK; done

gives that only HOST/hostname_nonfqdn@REALM is working...

enctype is my nightmare.

GPO not applying on XP

This is a real pain when you insert a Windows 2003 or an Windows XP in your Active Directory: GPO aren't correctly applied. This happens sometime, sometime not! In fact this is due to a boot to fast from XP. They have added some asynchronous service startup, and the network is part of that. You will get the login screen before network is up and all GPO are applied.

The detail from the startup can be found here

There is a easy solution for this problem: just make a synchronous start of service like Windows 2000:

Goup Policy : "Computer Configuration\ Administrative Templates\ System\ Logon" set "Always wait for the network at computer startup and logon" to "Active"
