I can't seem to be able to 'whitelist' this.  Adding

  samba4.rpc.echo against rpc proxy with domain creds\(rpc_proxy\)

or some variations to the knownfail list makes no difference. Adding
samba4.rpc.echo.* makes whole lot of false positives which also fails.

How to mark this failure as "known" properly?
