Script: Bash: TDS LDAP Restore

Below you'll find a script I've used to restore LDAP data which was backup with this script: Script: Bash: TDS LDAP Backup.

#!/bin/bash
#set -x
 
### Export HOME and APP Settings
export LDAP_INSTANCE=idsfop
export LDAP_HOME=/opt/IBM/ldap/V6.0
export LDAPSEARCH="${LDAP_HOME}/bin/ldapsearch"
export APPDIR=$LDAP_HOME
 
### Read LDAP Restore Instance Settings
LDAPUSER1="cn=Directory Manager"
LDAPBASE1="o=organization.nl"
 
echo
echo "Please provide Directory Admin DN [$LDAPUSER1]:"
read LDAPUSER
echo
echo "Directory Admin password:"
read LDAPPASS
echo
echo "Please provide application base DN [$LDAPBASE1]:"
read LDAPBASE
echo
echo "Please provide password of db2 user account (UNIX):"
read DB2PASS
 
### If LDAPUSER is empty then use default setting
if [ -z "$LDAPUSER" ]; then
   LDAPUSER="$LDAPUSER1"
   echo "LDAP user being used = $LDAPUSER1"
fi
 
### If LDAPBASE is empty then use default setting
if [ -z "$LDAPBASE" ]; then
   LDAPBASE="$LDAPBASE1"
   echo "LDAP base being used = $LDAPBASE1"
fi
 
### Get live DB2 Settings
getConfigValueFromLdap() {
   $LDAPSEARCH -D "$LDAPUSER" -w $LDAPPASS -h localhost -s base -b "cn=Directory,cn=RDBM Backends,cn=IBM Directory,cn=Schemas,cn=Configuration" '(objectclass=*)' $1 | grep $1 | awk -F= '{ print $2 }'
}
 
echo
DB2USER=`getConfigValueFromLdap ibm-slapdDbUserID`
echo "DB2 User being used = $DB2USER"
DB2INSTANCE=`getConfigValueFromLdap ibm-slapdDbInstance`
echo "DB2 Instance being used = $DB2INSTANCE"
LDAPDB=`getConfigValueFromLdap ibm-slapdDbName`
echo "LDAP DB being used = $LDAPDB"
DBLOCATION=`getConfigValueFromLdap ibm-slapdDbLocation`
echo "DB Location = $DBLOCATION"
 
### Check for empty variables
if [ -z "$DB2USER" -o -z "$DB2INSTANCE" -o -z "$LDAPDB" -o -z "$DBLOCATION" ]; then
   echo
   echo "`tput bold``tput smul`ERROR - Could not retreive configuration setting from LDAP, ABORTING!`tput sgr0`"
   echo
   echo "Possible causes: "
   echo " - incorrect credentials (Directory Admin)"
   echo " - incorrect application DN provided"
   echo " - Directory server not running or reachable"
   echo
   exit 1
