On Centos 7.5 I suspect he is talking about krb5-libs-1.15.1-19.el7.x86_64

Unfortunately on a Centos 7 machine it gets installed with at system creation
time and cannot be removed without breaking the system.

FWIW,
(vdc2 pts2) # rpm -qf /etc/krb5.conf
krb5-libs-1.15.1-19.el7.x86_64
(vdc2 pts2) #

For giggles I tried to rm it and I get an error when yum tries to rm the
dependencies.

As to the actual problem, my fully updated Centos-7.5 systems are functioning
normally after removing the stupid include line from /etc/krb5.conf.

All of this brings up a different question, Since I use self compiled Samba DCs
my machines have 2 krb5.conf files. One is obviously in /etc/ but the other is
in /usr/local/samba/private/. I know the Wiki says to copy the one in 
/usr/local/samba/private/ to /etc/ but does Samba use the one in 
/usr/local/samba/private/ for anything else other than to seed the one in /etc?

Could /usr/local/samba/private/krb5.conf be removed and still have samba
function properly. I do not want to actually rm it I am just trying to
understand how things work.
