strange moment in chroot environment

[Sergey Velikanov [UzPAK]]

Hi

I use "pw" in chroot environment, everything is work, but pw
always says that "unable to parse auth.conf", I've discovered that
error appear when pw call properties_read from libutil, I can't
understand why? I run "strace" twice, in chroot environment and normal
environment I discover next difference ( also difference I soo when
run proftpd in chroot and normal environments)

Could anybody help me to solve this problem.
