Bind to Open Directory Script

Question

I have been trying to come up with a script that I can run in ARD for each computer to bind to Open Directory. It seems like a hassle to log into each machine and bind it through Directory Utility. There are 10.4 and 10.5 machines as well as a few 10.3 on the network. The script I came up with is as follows:
dsconfigldap -u {USERNAME} -p {PASSWORD -l {LOCAL USERNAME} -q {LOCAL PASSWORD} -f -a {OD SERVER} -c {HOSTNAME} -n {OD SERVER}
sleep 20
dscl /Search -create / SearchPolicy CSPSearchPath
dscl /Search -append / CSPSearchPath /LDAPv3/fps-curry.wildwood.edu
exit 0
Some computers run the script with no errors, others do not. The error I get is this:
Cannot open remote host, error: DSOpenDirServiceErr
Data source (-l) is not valid.
Cannot open remote host, error: DSOpenDirServiceErr
Data source (-l) is not valid.

Answer 1

I am now getting the following error on some computers:
<main> attribute status: eDSNodeNotFound
This has something to do with adding the search policy. What is weird though is that sometimes if I run just the search policy again it will run without errors.
