Huh?  Noooo, no passwords/secrets in config files please.  The config
file should name a file where the secret(s) is(are) kept, which file
then can be made sure to be mode 0600 and handled (e.g., w.r.t.
backups, replication, ..., like any other file that contains sensitive
data.  And if there's any way to abuse keytabs (heh) for this, go for
it.

(This is a big deal at Sun^H^H^HOracle, in Solaris engineering and at
PSARC.  Or used to be.)
