When i try to add root.ldif file am getting this error Already exixts(68)

If suppose i had edited the root.file or any other ldif file which are already added

to the database,at that time also will i get the same error.

Just say me how to add the edited ldif file in the database.

 

[root@server openldap]# ldapadd -x -D "cn=Manager,dc=example,dc=com" -W -f /etc/openldap/root.ldif
Enter LDAP Password:
