[Samba] After joining domain, Samba uses the workgroup name, not the FQDN when running the net ads command
Thank you Rowland for the help so far. I followed the directions on that page very precisely. I was able to join the domain, but the RPC stuff still doesn't work and I'm still having the same problem. The actual root problem is that up to this point, winbind works for about a day or so then I start getting NT_STATUS_ACCESS_DENIED. Anyway, after the join, winbind works right now: sudo wbinfo -a administrator Enter administrator's password: plaintext password authentication succeeded Checking RPC: sudo net rpc info -Uadministrator Unable to find a suitable server for domain WINDOWS Here is my new config: /etc/hosts 127.0.0.1 localhost /etc/krb5.conf [libdefaults] default_realm = WINDOWS.CORP.XXX.COM /etc/samba/smb.conf [global] netbios name=freeradius security=ADS workgroup=WINDOWS realm=WINDOWS.CORP.XXX.COM log file=/var/log/samba/%m.log log level=1 dedicated keytab file=/etc/krb5.keytab kerberos method=secrets and keytab winbind refresh tickets=yes winbind trusted domains only=no winbind use default domain=yes winbind enum users=yes winbind enum groups=yes load printers=no template shell=/bin/false idmap config WINDOWS:backend=rid idmap config WINDOWS:range=10000-99999 On Mon, Nov 30, 2015 at 3:07 PM, Rowland Penny <rowlandpenny241155 at gmail.com> wrote:> On 30/11/15 20:52, Jonathan S.
