OK, what version Samba are using on the Unix domain member ?
If you are using 4.6 (or later), remove the 'winbind nss info' line.
If you are still using 4.5, then remove the 'idmap config
MIND:unix_info' line.

You do not need the the two 'winbind enum' lines to gete 'getent' to
work, 'getent passwd username' & 'getent group groupname' will work
without them.

If you had to add the above lines after the Badlock updates, don't you
think it is about time you fixed your DCs, it will be more secure. I
also cannot see the reason for adding them, the first line only
makes sense on a DC, the second turns off 'sign & seal' and the third
only makes Kerberos look in /etc/krb5.keytab.
