[rhn-users] Passwords generated on SUSE don't work on RedHat

[Pete Masse]

I wanted to do this at one time about six months ago but ran out of time and 
never found a way.  I'm sure it's out there.  In the mean time, md5 works 
great on both.

Thank you Pete and everyone else who responded.  Is it
possible to change Red Hat to use blowfish instead of
md5 as opposed to changing SUSE to use md5 instead of
blowfish?

Thank you.
