thanks a lot for your really super fast help. Running 'getent passwd' takes 
about 10s-40s, which is ok I think for 50000 entries. But mc keeps winbindd 
busy for at least 5-10 min, which is rather critical. This efficiently 
prevents other logins to this system at all. Well, mc is not the big deal, 
but our customer has experienced quite a lot problems in the past and I'm 
afraid they are doing something (don't know what), that does the same as mc.

Is there a way to increase disk cache of winbind? It presently takes 50MB, 
which I guess it too less. Or any other ideas how to tune it?
I know that winbindd from samba-3.0.25 is entirely rewritten in aspect to 
cache, will it also solve those problems?

Thanks again,
