This actually reveals something:
[user at s4member samba]$ ping _kerberos._tcp.dc._msdcs.samba.example.com
ERROR: ld.so: object 'libnss_wrapper.so' from LD_PRELOAD cannot be 
preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object 'libresolv_wrapper.so' from LD_PRELOAD cannot be 
preloaded (cannot open shared object file): ignored.
PING _kerberos._tcp.dc._msdcs.samba.example.com (54.72.52.58) 56(84) 
bytes of data.

It looks like a problem with LD_PRELOAD. The libraries are present, I 
don't know if this may be caused by them being in /usr/lib64 instead of 
/usr/lib or what else

I had found that, and fixed, thanks (it's python3-dns here, in addition 
to python2-dns which was already in)
(Another one missing was python3-markdown)

Done that too - still this error resists.
