Um, I tried your method for creating certs and it does
not work in FC4 - I think you might be surprised that
the "old way of doing things" has changed.  This is what
I was trying to tell you earlier.

First off, there is no /etc/ssl directory - I think this
is now /etc/pki

Second, the openssl is looking for /usr/share/ssl/openssl.cnf
of which /etc/share/ssl is no longer there.  I think they moved
things around so that openssl.cnf is now in /etc/pki/tls so
in order to get openssl to work, you may now need to define
where the openssl.cnf file on the command line.

openssl is probably being moved around.  I have NO CLUE what
is going on with openssl and FC4 - perhaps it is still a work
in progress.  dunno.

Another thing,  when I was doing kerberos and got it running,
there is a definite bug in /etc/init.d/ldap, line 74 where
kinit was not found.  The '$' was missing so that it should
be $kinit and not stand-alone kinit since the script does not
have the full pathname to kinit.

FC4 has a little ways to go to get things right again... sigh.

I will play around some more before I give it up altogther.

Thanks for your help tho!

Dan
