sshfs (which uses ssh) is used by default for mounting the user home directories when localapps or fat clients are used. That's because it's secure and easy (no server configuration needed). If you specify NFS_HOME, then sshfs automatically gets disabled. You're right about the nbd-proxy CPU usage, it's one of the reasons we decided against using it in our computer labs here. Nbd-proxy is only installed by default in Lucid/Maverick, to remove it see comment #13 in https://bugs.launchpad.net/ltsp/+bug/589034 > Too bad for me.

I can't think of an easy way to do it currently, apart from installing GDM in the chroot and also configuring the chroot to use LDAP. You'd lose all functionality provided by LDM, though. When sbalneav finishes implementing his pam_sshauth library, you should be able to do it with the stock login managers (LightDM, GDM etc) without configuring anything. ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
