samba4: machine and user accounts

[Mike Wilkinson]

Ok, got time to reprovision, replaced source/setup/schema.ldif with the 
extracted one from the domain.

dsdb/schema/schema_init.c:431: 'msExchMailboxManagerReportRecipient': 
unable to map attributeID 1.2.840.113556.1.4.7000.102.50076: 
WERR_DS_NO_MSDS_INTID

I picked a random oid from the the original schema.ldif to find if 
there's any lookup table or hard coded list, and I didn't find anything.

Any suggestions to where to go next?
