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. + */ + +#ifndef __BACKSQL_H__ +#define __BACKSQL_H__ + +/* former sql-types.h */ +#include <sql.h> +#include <sqlext.h> + +typedef struct { + SWORD ncols; + BerVarray col_names; + UDWORD *col_prec; + SQLSMALLINT *col_type; + char **cols; + SQLLEN *value_len; +} BACKSQL_ROW_NTS; + +/* + * Better use the standard length of 8192 (as of slap.h)? + * + * NOTE: must be consistent with definition in ldap_entries table + */ +/* #define BACKSQL_MAX_DN_LEN SLAP_LDAPDN_MAXLEN */ +#define BACKSQL_MAX_DN_LEN 255 + +/* + * define to enable very extensive trace logging (debug only) + */ +#undef BACKSQL_TRACE + +/* + * define if using MS SQL and workaround needed (see sql-wrap.c) + */ +#undef BACKSQL_MSSQL_WORKAROUND + +/* + * define to enable values counting for attributes + */ +#define BACKSQL_COUNTQUERY + +/* + * define to enable prettification/validation of values + */ +#define BACKSQL_PRETTY_VALIDATE + +/* + * define to enable varchars as unique keys in user tables + * + * by default integers are used (and recommended) + * for performances.

Build +To build slapd with back-sql under Unix you need to build and install +iODBC 2.50.3 (later versions should probably work, but not earlier), +or unixODBC (you will have to change -liodbc to -lodbc then). +Then, at top of OpenLDAP source tree, run +"configure <other options you need> --enable-sql", then "make" - +this should build back-sql-enabled slapd, provided that you have iODBC/unixODBC +libraries and include files in include/library paths, "make install"... +In other words, follow installation procedure described in OpenLDAP +Administrators Guide, adding --enable-sql option to configure, and +having iODBC/unixODBC libraries installed an accessible by compiler. + +Under Win32/MSVC++, I modified the workspace so that back-sql is built into +slapd automatically, since MS ODBC manager, odbc32.dll, is included in +standard library pack, and it does no bad even if you don't plan to use it. +I also could provide precompiled executables for those who don't have MSVC. +Note that Win32 port of OpenLDAP itself is experimental, and thus doesn't +provide very convenient build environment (yet). + +2. Tune datasources and slapd.conf +Next, you need to define ODBC datasource with data you want to publish +with help of back-sql. Assuming that you have your data in some SQL-compliant +RDBMS, and have installed proper ODBC driver for this RDBMS, this is as simple +as adding a record into odbc.ini (for iODBC/unixODBC), or using ODBC wizard in +Control Panel (for odbc32). +Next, you need to add appropriate "database" record to your slapd.conf. +See samples provided in "back-sql/RDBMS_DEPENDENT/" subdirectory. + +Several things worth noting about ODBC: +- "dbname" directive stands for ODBC datasource name (DSN), + not the name of your database in RDBMS context +- ODBC under Unix is not so common as under Windows, so you could have + problems with Unix drivers for your RDBMS. Visit http://www.openlinksw.com, + they provide a multitier solution which allows connecting to DBMSes on + different platforms, proxying and other connectivity and integration issues. + They also support iODBC, and have good free customer service through + newsserver (at news.openlinksw.com). + Also worth noting are: ODBC-ODBC bridge by EasySoft (which was claimed + by several people to be far more effective and stable than OpenLink), + OpenRDA package etc. +- be careful defining RDBMS connection parameters, you'll probably need only + "dbname" directive - all the rest can be defined in datasource. Every other + directive is used to override value stored in datasource definition. + Maybe you will want to use dbuser/dbpasswd to override credentials defined in datasource +- full list of configuration directives supported is available in file "guide", + you may also analyze output of 'slapd -d 5' to find out some useful + directives for redefining default queries + +3. Creating and using back-sql metatables +Read the file "concept" to understand, what metainformation you need to add, +and what for... ;) +See SQL scripts and slapd.conf files in samples directory. +Find subdirectory in "rdbms_depend/" corresponding to your RDBMS (Oracle, +MS SQL Server and mySQL are listed there currently), or copy and edit +any of these to conform to SQL dialect of your RDBMS (please be sure to send +me scripts and notes for new RDBMSes ;). + +Execute "backsql_create.sql" from that subdirectory (or edited one), +so that the tables it creates appear in the same +context with the data you want to export through LDAP (under same DB/user, +or whatever is needed in RDBMS you use). You can use something like +"mysql < xxx.sql" for mySQL, Query Analyzer+Open query file for MS SQL, +sqlplus and "@xxx.sql" for Oracle. + +You may well want to try it with test data first, and see how metatables +are used. Create test data and metadata by running testdb_create.sql, +testdb_data.sql, and testdb_metadata.sql scripts (again, adopted for your +RDBMS, and in the same context as metatables you created before), and +tune slapd.conf to use your test DB. + +4. Testing +To diagnose back-sql, run slapd with debug level TRACE ("slapd -d 5" will go). +Then, use some LDAP client to query corresponding subtree (for test database, +you could for instance search one level from "o=sql,c=RU"). I personally used +saucer, which is included in OpenLDAP package (it builds automatically under +Unix/GNU configure and for MSVC I added appropriate project to workspace). +And also Java LDAP browser-editor (see link somewhere on OpenLDAP site) to +test ADD/DELETE/MODIFY operations on Oracle and MS SQL. + +See file "platforms" if you encounter connection problems - you may find +a hint for your RDBMS or OS there.
