Samba4.11.1 on Ubuntu Server 19.10

I have compiled samba 4.11.1 on Ubuntu Server 19.10.

I have provisioned a domain, it appeared to complete successfully, the KRB5.conf generated by samba has been placed in /etc/krb5.conf as required.

Test smbclient:
Quote:

root@dc1:/home/tom# smbclient //localhost/netlogon -UAdministrator -c 'ls' Enter MIMOSA.LOCAL\Administrator's password: . D 0 Thu Oct 24 20:07:24 2019 .. D 0 Thu Oct 24 20:07:32 2019 20508240 blocks of size 1024. 13803532 blocks available

Though the DNS and kerberos checks below all fail:

Quote:

kinit administrator@MIMOSA.LOCAL kinit: Cannot find KDC for realm "MIMOSA.LOCAL" while getting initial credentials

Quote:

root@dc1:/home/tom# host -t SRV _ldap._tcp.dc1.mimosa.local. Host _ldap._tcp.dc1.mimosa.local. not found: 3(NXDOMAIN)

Can anyone advise? Have I posted enough information? If any more details are needed, I'll be happy to provide them....
