I didn't. Now I do.
That seems to help. After just 15 Minutes of the beginning of a new starting
lesson, the nscd --statistic shows me 968 positiv cache hits on passwd

I did that as well, but I am not shure if it helps. I have the feeling that

My user-base is a bit larger (4500 and such quite small AFAIK). Is it just
that up 100 user log in simultaneously.

That paper was very interesting and helped a lot (especially the nscd part).
The sysctl related values as fs.file-max were set by default much higher,
fs.file-max is 104851 in my case. There is no bottleneck in that realm on my
server, as far as I can see.
I still have periods of up to ten seconds (formerly 40) that my server is
100%busy. MS reports a slow server and discontinues to connect some drives.
Especially the "home" drive is concerned. I can't see any reason.
First I let nscd do some work and do some more analyzing, maybe the problem
is solved by now.
Thanks a lot,
