[Casper] Configure LDAP via DHCP

[Steve Wood]

In the Directory Utility application, when you open the LDAP service  
you can tell LDAP to get its information from DHCP.  I want to set  
that from a shell script.  Using defaults write was my first thought,  
but the plist that controls that setting is not in the domain ("Domain  
SearchNodeConfig.plist does not exist").  So, that means in order to  
"trip" the flag you need to edit the plist by hand.

Now, the plist contains information in this format:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd 
">
<plist version="1.0">
<dict>
	<key>DHCP LDAP</key>
	<dict>
		<key>/Sets/5FB6FAF4-3397-4981-BCC0-4D8FE463CA1C</key>
		<true/>
	</dict>
	<key>Search Node PlugIn Version</key>
	<string>Search Node PlugIn Version 1.7</string>
	<key>Search Policy</key>
	<integer>1</integer>
</dict>
</plist>


Notice the key "DHCP LDAP".  You need to set the value of the key to  
true, as it is here (<true/>), if you want to gather the LDAP info  
from DHCP.  Since I cannot use defaults write to do this, that means I  
have to use sed to parse out the key and then inject the true flag.   
BTW, the key value (in this case <key>/Sets/5FB6FAF4-3397-4981- 
BCC0-4D8FE463CA1C</key>) is different for each machine, so just  
dropping the plist into each machine won't work (I tried).

Hope that helps.
