So an "import" overwrites the entire database with what is in the LDIF
file.  What you want to do is to merge the data.  If there are not that
many entries in the LDIF the easiest solution is to use ldapmodify to
add each entry separately:

For example:

$ ldapmodify -D "cn=directory manager" -W -a -c -f <your LDIF file>

HTH,
