+ * The following changes have been addressed:

+ * Enhancements:
+ * - re-styled code for better readability
+ * - upgraded backend API to reflect recent changes
+ * - LDAP schema is checked when loading SQL/LDAP mapping
+ * - AttributeDescription/ObjectClass pointers used for more efficient
+ * mapping lookup
+ * - bervals used where string length is required often
+ * - atomized write operations by committing at the end of each operation
+ * and defaulting connection closure to rollback
+ * - added LDAP access control to write operations
+ * - fully implemented modrdn (with rdn attrs change, deleteoldrdn,
+ * access check, parent/children check and more)
+ * - added parent access control, children control to delete operation
+ * - added structuralObjectClass operational attribute check and
+ * value return on search
+ * - added hasSubordinate operational attribute on demand
+ * - search limits are appropriately enforced
+ * - function backsql_strcat() has been made more efficient
+ * - concat function has been made configurable by means of a pattern

+ * - fail_if_no_mapping write operations fail if there is no mapping
+ * - has_ldapinfo_dn_ru overrides autodetect
+ * - concat_pattern a string containing two '?' is used
+ * (note that "?||?" should be more portable
+ * than builtin function "CONCAT(?,?)")
+ * - strcast_func cast of string constants in "SELECT DISTINCT

+ * - upper_needs_cast cast the argument of upper when required
+ * (basically when building dn substring queries)
+ * - added noop control
+ * - added values return filter control
+ * - hasSubordinate can be used in search filters (with limitations)
+ * - eliminated oc->name; use oc->oc->soc_cname instead
+ *
+ * Todo:
+ * - add security checks for SQL statements that can be injected (?)
+ * - re-test with previously supported RDBMs
+ * - replace dn_ru and so with normalized dn (no need for upper() and so

+ * - implement a backsql_normalize() function to replace the upper()

+ * - note that subtree deletion, subtree renaming and so could be easily
+ * implemented (rollback and consistency checks are available :)
+ * - implement "lastmod" and other operational stuff (ldap_entries table ?)

+
+ Changes that were made to the SQL backend.
+
+The patches were made against 2.2.18 and can be applied individually,
+but would best be applied in the numerical order of the file names.
+A synopsis of each patch is given here:
+
+
+1. Added an option to set SQL query for the "id_query" operation.
+
+2. Added an option to the SQL backend called "use_subtree_shortcut".
+When a search is performed, the SQL query includes a WHERE clause
+which says the DN must be "LIKE %<searchbase>". The LIKE operation
+can be slow in an RDBM. This shortcut option says that if the
+searchbase of the LDAP search is the root DN of the SQL backend,
+and thus all objects will match the LIKE operator, do not include
+the "LIKE %<searchbase>" clause in the SQL query (it is replaced
+instead by the always true "1=1" clause to keep the "AND"'s
+working correctly). This option is off by default, and should be
+turned on only if all objects to be found in the RDBM are under the
+same root DN. Multiple backends working within the same RDBM table
+space would encounter problems. LDAP searches whose searchbase are
+not at the root DN will bypass this shortcut and employ the LIKE
+clause.
+
+3. Added a "create_hint" column to ldap_oc_mappings table. Allows
+taking the value of an attr named in "create_hint" and passing it to
+the create_proc procedure. This is necessary for when an objectClass's
+table is partition indexed by some indexing column and thus the value
+in that indexing column cannot change after the row is created. The
+value for the indexed column is passed into the create_proc, which
+uses it to fill in the indexed column as the new row is created.
+
+4. When loading the values of an attribute, the count(*) of the number
+of values is fetched first and memory is allocated for the array of
+values and normalized values. The old system of loading the values one
+by one and running realloc() on the array of values and normalized
+values each time was badly fragmenting memory. The array of values and
+normalized values would be side by side in memory, and realloc()'ing
+them over and over would force them to leapfrog each other through all
+of available memory. Attrs with a large number of values could not be
+loaded without crashing the slapd daemon.
+
+5. Added code to interpret the value returned by stored procedures
+which have expect_return set. Returned value is interpreted as an LDAP
+return code. This allows the distinction between the SQL failing to
+execute and the SQL running to completion and returning an error code
+which can indicate a policy violation.
+
+6. Added RDBM connection pooling. Once an operation is finished the
+connection to the RDBM is returned to a pool rather than closing.
+Allows the next operation to skip the initialization and authentication
+phases of contacting the RDBM. Also, if licensing with ODBC places
+a limit on the number of connections, an LDAP thread can block waiting
+for another thread to finish, so that no LDAP errors are returned
+for having more LDAP connections than allowed RDBM connections. An
+RDBM connection which receives an SQL error is marked as "tainted"
+so that it will be closed rather than returned to the pool.
+ Also, RDBM connections must be bound to a given LDAP connection AND
+operation number, and NOT just the connection number. Asynchronous
+LDAP clients can have multiple simultaneous LDAP operations which
+should not share the same RDBM connection. A given LDAP operation can
+even make multiple SQL operations (e.g. a BIND operation which
+requires SASL to perform an LDAP search to convert the SASL ID to an
+LDAP DN), so each RDBM connection now has a refcount that must reach
+zero before the connection is returned to the free pool.
+
+7. Added ability to change the objectClass of an object. Required
+considerable work to copy all attributes out of old object and into
+new object. Does a schema check before proceeding. Creates a new
+object, fills it in, deletes the old object, then changes the
+oc_map_id and keyval of the entry in the "ldap_entries" table.
+
+8. Generic fixes. Includes initializing pointers before they
+get used in error branch cases, pointer checks before dereferencing,
+resetting a return code to success after a COMPARE op, sealing
+memory leaks, and in search.c, changing some of the "1=1" tests to
+"2=2", "3=3", etc so that when reading slapd trace output, the
+location in the source code where the x=x test was added to the SQL
+can be easily distinguished.
