Hi,
I just installed ltsp based on Kubuntu Hardy Heron for our medium sized local
network (some dozens of parallel users).

It looks quite nice, thanks for the good work.

A problem, I ran into, concerns local devices and group handling. I followed
the hints in https://wiki.ubuntu.com/DebugLocalDev, which recommends to add
every user to group fuse.

I handle this with the pam_group module and also added the groups
plugdev,fuse,scanner,video,audio,cdrom for the corresponding services (e.g. 
'ssh -X <ltsp-client> k3b' for burning CDs needs group cdrom).

The (design-)problem is the number of needed groups, as we also use groups for
workgroup-cooperation.

Now we have the problem that I cannot access nfs-mounted directories although
I am member of the appropriate group. NFS has a limit of max. 16 groups, where
you can be a member of. If you are beyond this number you get 'access denied'.

An alternative solution is to rewrite lots of udev rules to change group
ownership or access rights of certain devices (e.g. /dev/fuse belongs to group
users or is 666 chmod-ed). This could have the disadvantage, that you have to
redo this work after every update.

Can you give me some hints, how to solve this most elegantly?

TIA
Helmut
