Turn off encryption from client to server?

[Todd O'Bryan]

Thanks to Scott Balneaves and Jim Kronebusch. Jim responded directly to me, probably bitten by the fact that the Reply button doesn't reply to the list. (Can I tell you how many times I've sent things to individuals, rather than a list, because of lists that make this choice...) I've included his answer below:

Download the new ldm from:

http://codebrowse.launchpad.net/~gideon/ltsp/gadi-ldm-mods-ltsp/download/gadi%40ltsp.org-20070521205254-ek710bofdpdtlwlz/x_Matt_Zimmerman_%3Cmatt.zimmerman%40canonical.com%3E_Tue_Jun__7_19%3A59%3A49_2005_32192.0/ldm

Then replace the current /opt/ltsp/i386/usr/sbin/ldm with the new one (make a backup
copy just in case).  Then modify your /opt/ltsp/i386/etc/lts.conf and add the following:

LDM_DIRECTX=True

Reboot your clients and you're ready to rock.
