[Samba] Unable to join to a SAMBA4 domain

[Sergio Belkin]

Hi folks

I'm using samba 4.8.3 in CentOS client and samba 4.9.3 from Van Belle repos
on server

I cannot join to the domain as

net ads join -k -d 1

libnet_Join:
    libnet_JoinCtx: struct libnet_JoinCtx
        in: struct libnet_JoinCtx

# End of outpout

Please could you help me to fix it?  I can provide more configs and outputs
if needed.

Thanks in advance
