In one word:
Tried it once and realmd moved the DC to the Computer OU in AD. There it
no longer is a DC and nothing worked for us...
As it is already joind you don't need realmd at all. Just configure
sssd.conf and start sssd.
However, I would not recommend that. We have since switched to winbind
as this is already running and with the sernet packages can not be
installed alongside sssd anyway.
