Binding into WM container

Hi, I administer a small lab of iMac's.  The AD server to which I bind is on a different subnet. Our network is part of a larger network.  I am putting together a method for imaging and maintaining the machines.  Because the machines are managed clients, they inherit all the preferences from the rules set on the WM container.  Currently, when I re-image the machines and rebind them, I have to manually drag them into the correct container in Workgroup Manager.  I am using dsconfigad to bind the machines, but I haven't figured out a way to put them into the correct container.  Is there another tool I can use that can achieve this?  Here is the basic framework of what I would like to do in the imaging process, unbinding and binding to AD as well as imaging.. Some bash is included. -All computers are running on 'Hard Drive' partition -Backup 'preferences.plist' -Unbind from AD domain & boot to '/Volumes/Tech' dsconfigad -remove -f -u [username] -p [password] bless -mount /Volumes/Tech -setBoot -nextonly shutdown -r now -Restore 'Hard Drive' & bless it asr restore --source asr://wherever.i.run.the.server --target '/Volumes/Hard Drive' --erase --noprompt --noverify --puppetstrings -Retore preferences backed up. And for sourcing the image: asr -source [path to image] -server [path to configuration plist] Rebinding to AD: (parameters are set) # Bind to AD (but is there a way to bind to correct container?) dsconfigad -f -a $computerid -domain $domain -u $udn -p "$password" -ou "$ou" # Restart DirectoryService killall DirectoryService # Add the AD node to the search path if [ "$alldomains" = "enable" ]; then csp="/Active Directory/All Domains" else csp="/Active Directory/$domain" fi
