the clients don't talk to ADs to resolve user information, only the
servers do. The clients only talk to AD DCs for authentication (to make
this a bit more complex, the authentication also involves parsing a
Kerberos PAC blob by the authentication helper in SSSD which also
includes the group memberships).
And unfortunately until RHEL-7.4 and SSSD 1.15 are out, then pinning the
SSSD on the IDM servers to a specific AD DC is only possible by
modifying the DNS SRV records or creating an AD site for the IDM server.
