Samba, Openldap and ppolicy

[smainklh@free.fr]

Hi,

I already have an openldap server configured with a password policy.
Now, i need to implement a samba server in order to authenticate my alfresco
users.

I would like to know how to keep my password policy working with these two
authentication services.
I've heard of the smbk5pwd but i don't know how to configure it.

I upgraded to slapd 2.4.23.

my slapd configuration :
include               samba.schema
...
moduleload        smbk5pwd.la
...
overlay    smbk5pwd

But when i start the slapd service, it complains that some ObjectClass are
missing.
Maybe Samba needs to be upraded too ? ...

I need your advices please.

Regards,
Smaine
