Does your code properly escape the backslash character as it writes to the database? IF you are NOT using 'cn=abc\\, def, ou=accounts' in your INSERT and UPDATE statements, you will get values that look like 'cn=abc, def, ou=accounts' in your data.
Without actual data, actual statements, a few lines of sample data, and the results of SHOW CREATE TABLE tablename\G, it's very hard to diagnose this problem further. Let's also move this discussion to the "General Discussion" ( mysql@lists.mysql.com) list as this problem does not seem to be related to any issue related to the server itself (yet). If it turns out to be a bug there is a separate list for those, too.
