[Samba] I can't join the new AD server with Samba4
Thanks for all your help. I've got the same error, then i think maybe is a problem related with upgrade. Maybe any wrong permissions or info on old samba server. I'll try to create a new domain with right data and migrate all machines (f ortunately are few computers). I think is the best.

[Samba] I can't join the new AD server with Samba4
Hi,
The smb.conf is the default after the upgrade:
cat /etc/samba/smb.conf
# Global parameters
[global]
workgroup = TTU
realm = ttu.red
netbios name = PDC
interfaces = lo, eth0
bind interfaces only = Yes
server role = active directory domain controller
server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl,
winbind, ntp_signd, kcc, dnsupdate
idmap_ldb:use rfc2307 = yes
[netlogon]
path = /server/samba/sysvol/ttu.red/scripts
read only = No
[sysvol]
path = /server/samba/sysvol
read only = No
and yes, it has a fixed IP.
I don't know if is important, but the dns backend is Bind 9.9. I've
tested
the dns with "samba_dnsupdate --verbose" and looks fine:

The krb5.conf is the linked version:
[libdefaults]
default_realm = TTU.RED
dns_lookup_realm = false
dns_lookup_kdc = true
and i can join the AD and use the RSAT tools with a Windows Machine.
