[Samba] Samba 3.5.5 with ldap backend crash slapd 2.4.23 !!!

[Frank Bonnet]

Hello

We use here Openldap 2.4.23 server running on a FreeBSD 8.1 server
compiled on the server from the FreeBSD ports. It runs well since
weeks.

We also use a Samba server 3.5.2 with ldap backend on a Linux
Debian Lenny server compiled from source on the server, everything
was running well ...

Last Monday I decided to upgrade the Samba server to the latest "Stable" 
release ( 3.5.5 )  then the nightmare begins ...

Few minutes after I restart ( reboot the server ) the samba server
the slapd daemon violently crashed.

After few restart it was still the same :

slapd works well if samba is stopped , Linux clients can authenticate
without problem, if I start samba daemons , windows clients begin
to connect and after few seconds slapd crash ...

Any infos welcome !
Thanks
