Configuration

These nodes are all under control of cfengine.

Master cfengine files for system configuration are located on ics.lsdf.kit.edu in directory /etc/cfengine/masterfiles/.

User Administration

Master files for user administration are located on ics.lsdf.kit.edu in /var/local/useradm. Here you will find a README containing specfic details. Basically the contents of the files in /var/local/useradm are entered in a DB. The DB is then send to the various nodes und control of cfengine.
