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

1542 This function compares to attribute names. Note that this is a
1543 case-insensitive comparison.
