This little cheat sheet describes some basic command you will need to use if your working with a debian system.
After wasting many days trying to get the following to work. I figured it out simply by watching a lot of ldap debug scrolling by.
Now in my case this is all running on Debian Squeeze but im sure it is similar with other Distro's possibly location and path's changing.
All this assumes you already have ldap running with SSL or TLS.
Make sure you have back-ports repository configured if you want a more recent version of the nvidia drivers which i highly recommend. Also the steps below need to be followed exactly so proper dependencies are met.
This will install kernel headers from stable
Step 1: apt-get install linux-headers-`uname -r`
This will pull in a more recent version of the Nvidia Driver from backports
Step 2: apt-get install -t squeeze-backports nvidia-glx nvidia-xconfig nvidia-kernel-dkms nvidia-settings
Step 3: nvidia-xconfig
