auth    optional        pam_group.so

• Add the following to the BOTTOM of /etc/security/group.conf:

# This will force all users that logon into these groups
login;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip
kdm;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip,video
gdm;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip,video

• Test LDAP authentication - if "id USERNAME" returns with info about the user... all is good. (Maybe)

root@clarke:~# id kmoorman
uid=1129(kmoorman) gid=110(faculty) groups=110(faculty),800(camp),2100(linux)

• Make sure you can log-in via KDM! See Potential Pitfalls.

• Need to alter /etc/nsswitch.conf

     Reorder all ldap files to compat ldap

Filesystems

• apt-get install nfs-common
• mkdir /classes
• mkdir /labdata
• Edit /etc/fstab

Add:

# NFS Filesystems
10.20.3.8:/data/exportfs/home           /home           nfs     defaults,rw
10.20.3.8:/data/exportfs/classes        /classes        nfs     defaults,rw
10.20.3.8:/data/exportfs/labdata        /labdata        nfs     defaults,rw

• Log-in to Babbage
• edit /etc/exports
• exportfs -a
• exit
• ssh root@IP
• mount -a
• Ensure the NFS filesystems loaded with "ls /home" "ls /classes" "ls /labdata"

Software

• scp 10.20.3.8:/root/keep/jdk* .

At Boot

• update-rc.d -f apache2 remove
• update-rc.d -f apparmor remove
• Edit /etc/rc.local - add echo "2147483648" > /proc/sys/kernel/shmmax

Remove Shutdown

• While logged in as root:
• mv /sbin/shutdown /sbin/shutoff
• The computer will now be unable to shut down except for the power button and calling the shutoff file like this:
• shutoff -h now

Potential Pitfalls

• The machine is frozen while trying to mount something! (Also: GDM freezes on start-up)

- Switch to terminal 1; if it works, then it's a GDM issue. GDM freezes on start up. Fix unknown; use KDM!

• When logging into an LDAP user on KDM, the log-in screen disappears but no welcome screen appears.

- Purge Plasma-Desktop and reinstall Plasma-Desktop / Kubuntu-Desktop. See http://ubuntuforums.org/showthread.php?t=2133661

• I keep getting a "??? ???" error during the initial install, after partitioning the hard drive

- The Ubuntu install does not understand RAID. In order to partition hard drives, you'll need to boot into the live CD (the first option when the installer comes up) and use GParted to partition the hard drive as you want. Reboot and install into whatever partition you like.
