Yes, and this part works. With esp= though, no matter what I've put in so
far, it's the same result as not putting in anything.> And aggrmode=yes?

I'm using the latest 2.3.1 RPMS for FC3.

I have "pfs=yes", but it doesn't like the "pfsgroup" statement. This is
also not in the manual...>

Makes sense, it's the same on the Windows clients too. This is why I want
to have all the values of esp= so that I can experiment on which one it
wants. If
