Student Login Versus Staff Login

PROBLEM: Distinguishing between staff and students logging in with OS X via LDAP and determining which location they are at.

SOLUTION: Using some unix commands, a loginhook was written to have the shell read the id of the user, as well as searching for the IP address of the server housing their home directory. This solution is based on the length of the user ID (with staff being 4 digits, and students 5 or 6) and the path of the home directory (either 10.2 for one building or 10.3 for another building), creating a desktop and items related to that user and that building. These values were obtained via LDAP from eDirectory.

Example

#/bin/sh

############################## desktop.sh ######################################
# Author    : Randy Saeks
#
# Purpose   : Run any items needed that are user related
# Calls     : /GBN/student.sh if UID > 9999 && $HOME contains 10.2
#	    : /GBN/staff.sh if UID < 10000 && $HOME contains 10.2
#	    : /GBS/student.sh if UID > 9999 $$ $HOME contains 10.3
#	    : /GBS/staff.sh if UID < 10000 && $HOME contains 10.3
