55 major restrictions as compared to normal LDAP:
57 - each record must have a unique key field
58 - the key must be representable as a NULL terminated C string and may not
59 contain a comma or braces
61 major restrictions as compared to tdb:
63 - no explicit locking calls, but we have transactions when using ldb_tdb
71 An individual lump of data in a result comes in this format. The
72 pointer will usually be to a UTF-8 string if the application is
73 sensible, but it can be to anything you like, including binary data
74 blobs of arbitrary size.
76 \note the data is null (0x00) terminated, but the length does not
77 include the terminator.
