Description of problem:
On an ldap migration, there is always problem when it is migrating the
services files, because there are 2 or more services have the same
name the the ldap server don't like that cn.

The problematic services are like 
echo

And often enough it will have some message like below
adding new entry "cn=echo,ou=Services,dc=example,dc=com"
ldapadd: update failed: cn=echo,ou=Services,dc=example,dc=com
ldap_add: Already exists (68)


Version-Release number of selected component (if applicable):
openldap-servers-2.1.29-1

How reproducible:
Everytime I do migration the same problem came to me (from Rh 7.3)

Steps to Reproduce:
1. Setup your ldap server (the slapd.conf)
2. start your ldap services
3. goto /usr/share/openldap/migration
4. make your change on migrate_common.ph so that it will be similar to
you slapd.conf (ldap server)
5. Now make the import by running ./migrate_all_online.sh And wait for
error like below.
adding new entry "cn=echo,ou=Services,dc=example,dc=com"
ldapadd: update failed: cn=echo,ou=Services,dc=example,dc=com
ldap_add: Already exists (68)
  
Actual results: 
import should finish as ususal.

Expected results:
No error will be there.
