Hi, I am running Samba 4 on FreeBSD 10 system. I recently upgraded from FreeBSD 10,1 to the latest 10.2 and thought I'd upgrade Samba at the same time. I have tested different versions of Samba (4.0.26, 4.1.18 and 4.2.3); everytime Samba will core dump at start. I get no error message. I tried to increase the debug level, not to avail. Smb.conf file is as follow, stripped to the bare minimum as I only need Active Directory so far. For the moment I am at lost on what I should try next and help would be greatly welcome. Best regards, Olivier # Global parameters [global] log level = 25 workgroup = SMB4 realm = CS.AIT.AC.TH netbios name = ACTIVE server role = active directory domain controller server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate [netlogon] path = /var/db/samba4/sysvol/cs.ait.ac.th/scripts read only = No [sysvol] path = /var/db/samba4/sysvol read only = No --
