I would expect writing less log should help avoiding problem. In this case, somehow logging must be set at certain or above a level. Below that it will trigger problem. While I was trying to get pieces working, I always set loglevel to 1 or -1. So I did not realize this problem until very late. The error I got as a result of attempting change password is "can't contact LDAP server" which is very confusing (might be because slapd already crashed before serving last request).

I am happy to run more tests and provide further information as needed.

If slapd crashes, the only really useful info is a core dump, as indicated in the FAQ I already pointed you to (that's basically why I pointed you there: there's no point in always repeating instructions for bug tracing, that's what the FAQ is intended for; apparently, it's totally ignored).

Adding one more information, the loglevel is 256 when the slapd crashed.

Command used: ldappasswd -v -H ldap://ldap2.example.com -D "uid=user,ou=people,dc=example,dc=com" -W -S -x -A
