Hi Im with a problem appeared when windows clients logins into my domain. I discovered how after to change the password in a user, the machine seems to be out from domain. Exactly retunrs this error "rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(546) _netr_ServerAuthenticate2: netlogon_creds_server_check failed. Rejecting auth request from client " Looking what can happen I discovered this thread https://lists.samba.org/archive/samba/2013-June/174085.html Seems to be exactly the same error, but checking my bind configuration I receive root at pdc:/# dig @dns domain ; <<>> DiG 9.5.1-P2.1 <<>> @10.0.0.254 esci ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58423 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;domain.
