Each thread will open a separate thread-local LDAP connection. Also a pool-size of 50 will put a lot of unnecessary pressure on your database. In general don't increase the pool size unless you are absolutely sure it is necessary. That said, it looks like you found a bug. I'll try to reproduce this. ---------------------------------------------------------------------- (0003606) frenice (reporter) - 08-Nov-13 12:53 http://dbmail.org/mantis/view.php?id=1028#c3606 ---------------------------------------------------------------------- Thank you.
