Yes.

No. Real X.500 servers store by OID, most LDAP servers don't. They use the
string names, so if you undefine the name you may lose access to the data.

If both names are defined, it doesn't matter which you use. Generally the
slapd code will  try to use the shortest name when it returns it to you
though.
