This is, in my opinion, red-hats attempt to lock you into their tools,
you do not need 'realmd', 'sssd' etc.

No idea, never used it, but it probably would work, but what is wrong
with 'net ads join' ?

Again, I know little about Selinux, but surely the native tools will
help here ?

The problem is that to get a fully working AD DC, you need to use
Heimdal and this isn't red-hats default, so I can sort of understand
krb5.conf being handled correctly, but sssd is their product, so if
this isn't being handled correctly, then, well, words fail me ;-)

I repeat, just in case anybody missed it, you do not need sssd on a
Samba machine, the Samba tools will do virtually anything it can do and
what they cannot do is easily done by other methods e. g. use sudo-ldap
