Directory Binding Script (Active and Open Directory) 10.7
Hi everyone
I'm reposting this in the right thread. I've written a Directory Binding Script for 10.6 and ported it now to 10.7 as among the things that have changed in the upgraded version is a refurbished directory binding enviroment.
The original thread can be found here: https://discussions.apple.com/thread/3090068. The script is applicable for clients as well and simplifies the binding process considerably.
Be aware that the reformatted script here contains some faulty line breaks. So you'll have to correct them in a proper text editor.

## Script to automate OD and AD Binding of Mac OS X 10.7 Servers
## Script written by Marc Horat, URZ Basel, 11.6.2010
## Updated: 12.08.2011
# With the use of the following sources as inspiration:

# Bombich's AD-Bind Script:
# This script binds to AD and configures advanced options of the AD plugin
# As this scripts contains a password, be sure to take appropriate security
# precautions
#
# A good way to run this script is to set it as a login hook on your master machine
# Because it only needs to be run once, the last thing this script does is to delete
# itself. If you have another login script that you typically run, include the
# script on your master machine, and indicate its path in the "newLoginScript"
# variable.
#
# If running this as a one-time login hook to bind to AD after imaging,
# be sure to enable auto-login (for any local user) before creating your master image
