Could you attach raw AVC message? Also what does # id -Z # ps -eZ |grep system_dbusd after login? id -Z
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
ps -eZ | grep system_dbusd
system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 1032 ? 00:00:00 dbus-daemon
I hope this is the right AVC message:

Retested with the beta fedora 16 release and selinux-policy-targeted-3.10.0-36.fc16.noarch. Still get failed login. The avc's are:

Actual results: Expected results: Additional info: Did not see avc until we diabled autofs and hard mounted nfs home directories. Fix with the following policy: module mysystem 1.0; require { type nfs_t; type system_dbusd_t; class file read; } #============= system_dbusd_t ============== allow system_dbusd_t nfs_t:file read;
