Comment 2 Daniel Walsh 2008-07-16 13:48:20 UTC
/etc/X11/xdm/authdir/authfiles directory should be writable (file "A:0-EQRIz0"
is created in this case)

I have no idea what these files are, none of these files/directrories exist when
I install fluxbox?  They are in a horrible location.  Variable files should be
in /var/run/fluxbox?  /var/lib/fluxbox?

If this is authorization data, you could choose:

/var/lib/abl(/.*)?	system_u:object_r:var_auth_t:s0
/var/run/xauth(/.*)?	system_u:object_r:xdm_var_run_t:s0
/var/lib/pam_ssh(/.*)?	system_u:object_r:var_auth_t:s0
/var/run/pam_ssh(/.*)?	system_u:object_r:var_auth_t:s0
/var/run/saslauthd(/.*)?	system_u:object_r:saslauthd_var_run_t:s0
/var/cache/coolkey(/.*)?	system_u:object_r:auth_cache_t:s0

Or create a new one.

/var/log/[kw]dm\.log.*	--	system_u:object_r:xserver_log_t:s0
/var/log/gdm(/.*)?	system_u:object_r:xserver_log_t:s0
/var/log/Xorg.*	--	system_u:object_r:xserver_log_t:s0
/var/log/XFree86.*	--	system_u:object_r:xserver_log_t:s0
/var/log/nvidia-installer\.log.*	--	system_u:object_r:xserver_log_t:s0

xserver log should match one of these I would think?  /var/log/Xorg.0.log seems
to be the way gdm does it.

What pam module does fluxbox use?  Does it include pam_selinux?
