Hi Bron,

I tried to find out more but with no success. Here is what works and what
not:

x86_64 works OK:
localhost.localdomain> lam system
group:leitung lrswipkte
simat lrswipcda
gamat lrswipcda
anonymous p

i386 does NOT work:
localhost.localdomain> lam system
anonymous p
anyone lrs


i386 works OK:
localhost.localdomain> lam system
anyone lrsp

Regards,
Simon
