Hi there,
I am very close to the solution, now:
- ldap/nfs overload is due to crashing nscd on ltsp.
- these crashes are now compensated by starting nscd
via cronjob every 5 min.
- nscd depends only on libc6
- as opposed to the original skolelinux version 2.2.3,
installed on my ltsp I found libc6 (2.3.2.ds1-18)

I don't know exactly where I got it from (downgrading would remove
nearly everything!), but "gg: 2.3.2.ds1-18 libc6" gives me segfault
reports as first hit!

Furthermore it seems to be from unstable (!)
