You could try a forced sync from nextcloud with 'samba-tool drs replicate' using the '--sync-forced' switch Rowland I tryied --sync-forced : got some error , but also say Replicate Succesful root at nextcloud:/var/lib/samba# samba-tool drs replicate nextcloud landc dc=domain,dc=lan --sync-all --sync-forced GSS client Update(krb5)(1) Update failed: Miscellaneous failure (see text): FAST fast response is missing FX-FAST (ldap/NEXTCLOUD at DOMAIN.LAN) GSS client Update(krb5)(1) Update failed: Miscellaneous failure (see text): FAST fast response is missing FX-FAST (ldap/nextcloud at DOMAIN.LAN) Replicate from landc to nextcloud was successful. what can I do now? we 've already removed samba and the whole /var/lib/samba on nextcloud DC and reinstalled .... no luck ! any suggestion? thank's rf Corso Martiri della Liberazione 114 - 23900 Lecco - ITALY - | 4801 Glenwood Avenue - Suite 200 - Raleigh, NC 27612 - USA - Tel +39 0341 220 205 - info.it at yetopen.com | Phone +1 919-817-8106 - info.us at yetopen.com Think green - Non stampare questa e-mail se non necessario / Don't print this email unless necessary -------- D.Lgs. 196/2003 e GDPR 679/2016 -------- Tutte le informazioni contenute in questo messaggio sono riservate ed a uso esclusivo del destinatario.
