is libldap using schema files?

Hi!

There is a question, which is totally dark for me.
Is libldap using the schema files I specified in config file?
If not, then from where is it know, what are the oid-s of my private
attributes and objectclasses?
Or it is sending all in text, and only the server translates them to oids?

ps: If I know it well, the attributenames arent case-sensitive. But
openssl's X509_NAME_add_entry_bx_txt IS case sensitive for its second
attribute (field). Why?
