Hi, I setup a test envirement on a dedicatet server. OS: debian stretch samba: 4.5.8 smbclient: 4.5.8 I set it up as DC, the provision work well, yes I've delete the smb.conf in advance. When I test kinit I got an kerberos ticket, but I've problems with smbclient either I use kerberos or password auth. Myabee someone could help me? my smb.conf: # Global parameters [global] netbios name = MX01 realm = RABADANTEN.DE workgroup = RABADANTEN dns forwarder = 8.8.8.8 server role = active directory domain controller [netlogon] path = /var/lib/samba/sysvol/rabadanten.de/scripts read only = No [sysvol] path = /var/lib/samba/sysvol read only = No my krb5.conf: [libdefaults] default_realm = RABADANTEN.DE dns_lookup_realm = false dns_lookup_kdc = true when I try with 'smbclient -L localhost -UAdministrator -d3' : <start> lp_load_ex: refreshing parameters Initialising global parameters rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[global]" added interface eth0 ip=2a02:248:2:32b3:5054:ff:fe80:7b7 bcast= netmask=ffff:ffff:ffff:ffff:: added interface eth0 ip=195.62.123.31 bcast=195.62.123.31 netmask=255.255.255.255 Client started (version 4.5.8-Debian).
