Yes.

Have a look at libraries/libldap/schema.c; you'll find a bunch of routines:
ldap_str2syntax, ldap_str2matchingrule, ldap_str2attributetype,
ldap_str2objectclass and so on, with the corresponding *_free stuff.
You can use them to parse the results of searching the schema from
a server.  You'll need to get the attributes in an objectClass and,
for each attributeType, the related syntaxes to ensure you're appropriately
handling the values.

They're documented in doc/man/man3/ldap_schema.3 (in the HEAD code, 
at least).
