Problemy z passwd (PAM, SELinux?)

[Michał Łukaszek]

Mam problemy z passwd. Nie pozwala zmienić hasła dla usera, wyświetla błąd
passwd: dlopen() failure

# rpm -qa | egrep 'selinux|policy'
policycoreutils-1.10-1
policy-sources-1.10-0.3
libselinux-1.10-1
policycoreutils-tools-perl-1.10-1
libselinux-devel-1.10-1
checkpolicy-1.10-1
libselinux-utils-1.10-1
policy-1.10-0.3

# rpm -qa | grep -i pam-
pam-0.77.3-11
pam-devel-0.77.3-11

Poniżej końcówka strace passwd dla jednego z userów. Martwi mnie to
ENODATA...
