Error -14278 during dsconfigldap bind

Hello I'm using a script to bind a collection of 10.6 Macs to a local 10.5 OD server. Sometimes, during the bind, I get a weird error back from the OD server. It is random and, if I wait a few hours and try again, that Mac will usually bind OK. Here my bind string followed by the verbose logFile results: ----- dsconfigldap -f -n "Primary" -a $odmaster -c MAC_NAME -u $oduser -p $odpassword -l $localAdmin -q $localAdminPassword -v >> $logFile ----- Binding Mac to OD server blah.blah.blah dsconfigldap verbose mode Options selected by user: Force authenticated (un)binding option selected Add server option selected Server name provided as LDAP Configuration name provided as Computer ID provided as Network username provided as Network user password provided as Local username provided as Local user password provided as Step 1 - Server Information Discovery Status: Success - Server Responded.
