ipa-adtrust-install fails with ipa : CRITICAL CIFS services failed to start

Good Afternoon,

I've been stuck on this issue for most of the day, systemctl status smb.service reports:

â smb.service - Samba SMB Daemon

but I've
ipa service-add cifs/.@
and
ipa-getkeytab -s . -p cifs/. -k /etc/samba/samba.keytab
/etc/dirsrv/ds.keytab
/etc/krb5.keytab

Any help would be most appreciated!
Thank you,
