[Samba] Samba 4.7.2 + bind on Fedora 27: samba_dlz: spnego update failed
I have setup on Fedora 27 server a AD-DC samba server + bind + dhcp.
All seem work fine: I can join to domain, add/remove dns records with
samba-tools, access to shared folder, use MS Management Console on
Win7, ecc
But when I join a new machine Samba winbind Member server to domain
[ root at server-dati ~]# net ads join DOGMA-TO -U administrator
Using short domain name -- DOGMA-TO
Joined 'SERVER-DATI' to dns domain 'dogma-to.loc'
DNS Update for server-dati.dogma-to.loc failed: ERROR_DNS_UPDATE_FAILED
DNS update failed: NT_STATUS_UNSUCCESSFUL
or run this command on Samba AD-DC:
[ root at server-addc ~]# samba_dnsupdate --all-names
--fail-immediately
update failed: REFUSED
Into system log I get:
dic 04 10:14:52 server-addc.dogma-to.loc named[7839]: samba_dlz: starting
transaction on zone dogma-to.loc
dic 04 10:14:52 server-addc.dogma-to.loc named[7839]: samba_dlz: spnego

dic 04 10:14:52 server-addc.dogma-to.loc named[7839]: samba_dlz: cancelling

What kind of problem it's?
