Resolves: #456752

Summary: GER: supporting "dn" and extensible object class is missing
Description:
1. Extensible object class cannot use the schema info. Evaluate existing
attributes with no schema check.
2. dn is not an attribute belonging to an entry, but treat is as it is if it's
given as a part of the attribute list.
