steel belted radius

just a few questions, as the funk steel belted radius (SBR) is recommended as RADIUS in the docs.

i found, that SBR uses a completely different directory scheme nor does have a standard dictionary file import.
are the mikrotik directory files included with SBR?
or is there somewhere a microtik.dct and .ini file for SBR?

if it’s “no” to all, why is SBR recommended?

i found too, that mikrotik is not mentioned anywhere on the SBR website.
