Thanks, Edmundo,
Thanks, John,

The difference between a BDC and a member server seems to be mainly
that a BDC can jump in for a crashed PDC and a server member can't.
That means a little more careful configuring but if that would stop it from
barking

   unable to map SID: S-1-5-21-NOTORIOUS-DOMAIN-SID-myRID

it would be worth the trouble. Are there performance reasons against
promoting 4 member servers to BDCs to equalize the SIDs?

Tu put it in different words: why would a joined member server still
have problems identifying a regular domain-Joe?
