Attached patch fixes a couple of issues with the script:

Manually add relevant objectClass attribute to attributes
(attributeSchema) and classes (classSchema) to the output.
(The ADA/ADSC docs do not contain this attribute).

Translate oMObjectClass attribute contents to binary octet string.

Fix bug when reading multivalued attributes from a LDIF file.

It still does not provision, however, now I'm seeing this error during
make test:

dsdb/schema/schema_init.c:697: 'gecos': unable to map attributeID WERR_DS_NO_MSDS_INTID
Traceback (most recent call last):
  File "./setup/provision", line 183, in <module>
  File "bin/python/samba/", line 1025, in provision
  File "bin/python/samba/", line 758, in setup_samdb
  File "bin/python/samba/", line 1544, in load_schema
    samdb.attach_schema_from_ldif(head_data, schema_data)
  File "bin/python/samba/", line 188, in attach_schema_from_ldif
    misc.dsdb_attach_schema_from_ldif_file(self, pf, df)
RuntimeError: (8596, 'WERR_DS_NO_MSDS_INTID')

Unfortunately, I'm not familiar with prefixMap.txt contents. MS-ADA3
describes the attribute as "internal use only".
FWIW, 'gecos' is a new attribute in the generated schema.ldif.
