+1) driver name comparison for MS SQL Server workaround is realy kinda dirty
+ hack, but for now i don't know how to code it more carefully
+2) another dirty hack: length of LONGVARCHAR and LONGVARBINARY fields is
+ currently set to MAX_ATTR_LEN. Maybe such fields must be handled with
+ SQLGetData() instead of SQLBindCol(), but it is said in documentation,
+ that it is guaranteed to work only when such column goes after last bound
+ column. Or should we get ALL columns with SQLGetData (then something like
+ _SQLFetchAsStrings() wrapper would do SQLGetData() for all columns)...
+4) in some cases (particularly, when using OpenLink Generic ODBC driver with
+ MS SQL Server), it returns "Function sequence error" after all records are
+ fetched. I really don't know what it means, and after all
+ - it works with any other driver I tried
+5) referral handling. this bug actually addresses all backends, as I can
+ understand. draft-ietf-ldapext-namedref-xx.txt says that referral should be
+ returned for ANY object containing "ref" attribute. And is_entry_referral
+ macro designed for "referral" objectclass only. This limits usability of
+ referrals too much. For instance, I could want to replicate some subtree on
+ another server, storing just "searchable" attributes + referral to full
+ object, and then use this subtree as kind of index for query routing.
+ If search returns referrals only for "referral" entries - I cannot do such
+ thing
+6) DO NOT EVER USE -O2 option (or any other optimization) under Un*x/gcc!!!
+ I have spent days trying to catch weird bugs, which went gone with optimization off
+7) The same thing that works on RedHat 6.0 (glibc 2.1.1), dumps core on
+ 6.1 (glibc 2.1.2) (the same code behaves differently when built on 6.0 and 6.1)
+ my problem was solved by upgrading iODBC to 3.0 beta - but it is kinda strange
+ that beta works better than release (and release still works fine on 6.0)
+8) Oracle does case-sensitive comparison of strings by default, so back-sql
+ becomes sensitive too when using Oracle. Later I'll add some option to slapd.conf
+ that would allow to set some function to process values before comparison
+ (something like "before_match UPPER", so that back-sql could generate
+ something like "select ... from ... where ... and UPPER(colname)=UPPER(?) or
+ UPPER(colname) LIKE UPPER(...)")
+9) ldapsearch sometimes refuses to show some attributes ("NOT PRINTABLE" diags)
+ on Win32 (on linux everything's fine -- at least with mySQL)
