I don't think the modifications I did to smb.conf are relevant enough to
cause problem, but here's our smb.conf, just in case:

# Global parameters
[global]
    workgroup = TRS-CH
    realm = TRS-CH.COM
    netbios name = PDC
    server role = active directory domain controller
    server services = +s3fs, +rpc, +nbt, +wrepl, +ldap, +cldap, +kdc, +drepl,
                        +winbind, +ntp_signd, +kcc, +dnsupdate 

[netlogon]
   path = /var/lib/samba/sysvol/trs-ch.com/scripts
   read only = No

[sysvol]
   path = /var/lib/samba/sysvol
   read only = No
>do you have ntp installed and configured correctly ?Yes, I have it installed and everything works fine.

I also already tested the DNS by running the commands described here:
https://wiki.samba.org/index.php/Setup_a_Samba_Active_Directory_Domain_Controller
Everything is reachable.

I tested kerberos by doing:
'kinit administrator at TRS-CH.COM'
It showed up when I did 'klist'.

Do you need more information ?

Thanks !

Are you running with Bind9 ?

I think you need to remove all the '+' signs you have added to the 
'server services' line, you normally only use the '+' sign to
add a
service to the line, I think you may still be using the un-shown 'dns' 
option.
I would also recommend that you use the new separate 'winbindd' instead 
of the 'winbind' that you are using. I think that before long the old 
'winbind' built into the samba daemon is going to disappear, so you 
might as well get used to it now.

OK, I have just joined a new DC to my domain and I am using Bind9 and 
this is what I have in smb.conf:

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, 
winbindd, ntp_signd, kcc, dnsupdate

Note the lack of '+' signs

This is with Samba 4.3.1

I have also checked and 'net ads info' works as well, so if yours
isn't
working, then something else is wrong, can you post your ntp.conf and 
bind9 conf files, also your /etc/resolv.conf & /etc/krb5.conf

[Samba] net ads info: failed to get server's current time

I have no "server services" line in my smb.conf and "net ads
info" is
working well using DC running Samba 4.3.1 on Centos 7.

Did you tried without "server services" line?

Cheers,

mathias

[Samba] net ads info: failed to get server's current time

Hai, 


Copy the code and Set these variable
Run the script, restart samba and login again with an pc. 
Should work now, your missing something and. Your not using good ntp servers.

#!/bin/bash 
########## NTP Settings needed for a correct funtioning samba AD DC server
## Set to 1 installs the ntp server. (default is ok )
## (default is ok )
NTPD_INSTALL="1"
# if you run the server on a XEN Server, set to 1.
NTPD_XEN_GUEST="0"
## important look for a stratum 1 server in your area
## for a server joining a domain put the ip of the AD server here.
## see also http://support.ntp.org/bin/view/Servers/StratumOneTimeServers
## (default is not ok, change this one to a ntp in your country )
NTPD_SERVER1_EXTERNAL="ntp1.nl.net"
## if you dont have a second ntp server leave empty
NTPD_SERVER2_EXTERNAL=""
## restrict ntpd bind to which interfaces.
## choose, multple options are allowed.
## the options are:  lo eth(0..9) wildcard ipv6
## (default is ok, if you interface name is eth0 and you dont use ipv6. )
NTPD_RESTRICT_INTERFACE="lo eth0"
NTPD_RESTRICT_INTERFACE_IGNORE="wildcard ipv6"
## default for sernet samba and debian samba ( should normaly not be changed )
SAMBA_NTP_SIGNPATH="/var/lib/samba/ntp_signd"
## debian default, leave it as is.
