Summary of changes: - filter -> SQL translation bugfixes - several memory leaks fixups - improved configurability: - allows definition of uppercasing function to support CIS matching on databases that do case sensitive compares (this fixes up Oracle issues, example updated) - allows more flexibility in stored procedures interface (different parameter order, optional return codes - see samples, and comments in backsql.h) - synchronize function interfaces to recent changes in prototypes ("const" clauses etc.) made for all backends (those changes led to compile-time errors)

Final run of changes to back-sql; IBM db2 support has been tested. Now related ITSes need be audited and possibly closed. 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) 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 ?)

extern BI_connection_destroy backsql_connection_destroy;
changes for 2.0-beta including: - fixes according to new API changes - closing db connection in connection_destroy callback, not unbind - support of new schema code, samples changed accordingly - support for multiple objectclasses (to distinguish from unique objectclass-to-tables mapping) - auto 'ref' attribute support - samples now include illustrations of using these 2 features to make named referrals as described in ldapext-namedref draft more to come: - documentation update - different improvements to be more close to native directory (after beta?)
