Samba, Openldap and ppolicy

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
