Description of problem: After kernel upgrade from version 2.6.19-1.2911.6.5.fc6 to 2.6.20-1.2925.fc6 oidentd doesn't return idents to masquared connections anymore. This is because in the kernel 2.6.20.x there are /proc/net/ip_conntrack no more (huh? w.f?!). It is now called /proc/net/nf_conntrack. Version-Release number of selected component (if applicable): oidentd-2.0.8-2.fc6
Moreover, the file syntax changed a little bit.
We need to enable backwards-compatible /proc and sysctl entries: NF_CONNTRACK_PROC_COMPAT=y
