Beware the use of the new password scheme if this is a NIS master server
and you have any NIS clients that aren't RH/Fedora (recent) machines.  I
have a mixed bag of AIX, SunOS (8 and 10), and Linux (old RH and newer
Fedora) and I had to force the use of the old password algorithms as
SunOS 8 and older AIX can't handle the new scheme.
