• auth-client-config -a -p transy
• Add the following line near the very top of /etc/pam.d/kdm AND /etc/pam.d/login

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.

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* .

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
