/*
* 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
* - added config switches:
* - 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
* statements (needed by PostgreSQL)
* - 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
* in dn match)
* - implement a backsql_normalize() function to replace the upper()
* conversion routines
* - 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 ?)
* - check how to allow multiple operations with one statement, to remove
* BACKSQL_REALLOC_STMT from modify.c (a more recent unixODBC lib?)
