Hello,
Doing this sequence crash the slapd server everytime.

/usr/lib/slapd -d 99
(switch console)
ldpadsearch
=>seg fault the server

If doing ldapserach -x
everything is fine.

Tell me if you need something more.
SASL is absolutly not well set up because
it is very obscure in doc/explanation. So maybe
the ldap server or ldapserachclient uses
something wrong. If this helps you avoid the
crash...

Bye
