Active Directory use multiple kerberos hashes with different encryption type and a NTLM hash and they are store in the supplementalCredentials attribute (which is neither readable of writable directly through LDAP). If you want to pipe a password hash from an OpenLDAP to a Samba-AD, the only solution is to have the NTLM hash and use the pdbedit --set-nt-hash command line on the domain controller. It will store the NTLM hash and create a derivative kerberos hash from that NTLM hash. Another solution is to use a webgui for password change and change the password both in OpenLDAP and Samba-AD from that webgui script. If it is possible to let Samba-AD handle all password change, then you can ask Samba to create different password hashes when someone changes its password from its Windows workstation. Then you can pipe the hashes in OpenLDAP from the Samba-AD.

Whilst you cannot read the unicodePWD attribute over ldap, you can set it via ldap. you need to do it as a modify, first delete the existing unicodePWD attribute and then add the new one. The password must be base64 encoded inside double quotes. Finally, you must do all of this over SSL. Rowland
Actually, i can update unicodePwd through LSC, and new password is working for authentication. This is the intended feature, so problem seems solved. -- Sébastien BEAUDLOT Université d'Avignon et des Pays de Vaucluse -- ----- Mail original ----- De: "samba" <samba at lists.samba.org> À: "samba" <samba at lists.samba.org> Envoyé: Vendredi 28 Septembre 2018 12:16:41 Objet: Re: [Samba] Synchronizing passwords to Samba 4 On Fri, 28 Sep 2018 11:49:47 +0200 Denis Cardon via samba <samba at lists.samba.org> wrote:> Hi Sébastien, > > >> I'm trying to synchronize user accounts from LDAP to Samba 4 AD > >> (using LSC) but it seems that password update through ldap is not > >> allowed. > >> > >> I failed to find details about it, but can someone confirm that > >> unicodePwd cannot be read / wrote trough a LDAPS connection ?
