Hello guys: I'm running two Zentyal servers with Samba 4.1.17 on each one. We're experiencing some problems such as: - When a user changes his password, it is not replicated the change on secondary DC. - Some Windows machines have reported trust relationship broken. On DC1 I run this: params.c:pm_process() - Processing configuration file "/etc/samba/shares.conf" ldb_wrap open of secrets.ldb GENSEC backend 'gssapi_spnego' registered GENSEC backend 'gssapi_krb5' registered GENSEC backend 'gssapi_krb5_sasl' registered GENSEC backend 'schannel' registered GENSEC backend 'spnego' registered GENSEC backend 'ntlmssp' registered GENSEC backend 'krb5' registered GENSEC backend 'fake_gssapi_krb5' registered Using binding ncacn_ip_tcp:dc01.mycompany.corp[,seal] Default-First-Site-Name\DC01 DSA Options: 0x00000001 DSA object GUID: 0a3adb77-a18e-4284-94f6-97c169e8d7f4 DSA invocationId: 055634e1-d57e-45de-bed8-4f57e001e992 ==== INBOUND NEIGHBORS === DC=ForestDnsZones,DC=mycompany,DC=corp Default-First-Site-Name\DC02 via RPC DSA object GUID: 65ff32e1-30a4-4697-a83f-d32815f31035 Last attempt @ Mon Apr 10 10:02:16 2017 PET failed, result 2 (WERR_BADFILE) 21101 consecutive failure(s).
