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