+ISSUES THAT YOU WILL PROBABLY STUMBLE ACROSS ANYWAY

1. 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).
+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
+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 --enbale-sql option to configure, and
-having iODBC libraries installed an accessible by compiler.

Under Win32/MSVC++, I modified the workspace so that back-sql is built into
-slapd automatically, since MS 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).
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), or using ODBC wizard in

Next, you need to add appropriate "database" record to your slapd.conf.
