With 2.4.23, i ran into the bug in IDS#6607 "Forwarded bind failure messages cause success", but was able to fix it by applying the minor diff of back-ldap/chain.c rev 1.77 (as was mentioned in the bug follow-up).
I've downloaded RE24 as of today & compiled it up. However, the bug is still there. Is this fix going to make it into 2.4.24 by any chance?
