authentic = 'realistic in one's attitudes'

[Jonathan Lighter]

A self-improvement author on CNN just now was explaining how to bounce back
from setbacks.  Rule Number One is, "Be authentic."  This was so important
that the words replaced the people on the screen for several moments.  But
it was clear from the discussion that "authentic" meant 'realistic,' or at
least 'candidly truthful with yourself.'  Being "authentic" meant not
assuming that there's something horribly wrong with you personally, "being
humble," etc., etc.

At any rate, not in OED.
