Description Dilamar Martinez 2010-02-02 00:18:28 UTC
Resúmen:

SELinux is preventing /usr/bin/kdm "write" access on /root.

Descripción Detallada:

[SELinux esta en modo permisivo. Este acceso no fue denegado.]

SELinux denied access requested by kdm. It is not expected that this access is
required by kdm and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Permitiendo Acceso:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

audit2allow suggests:

#============= xdm_t ==============
#!!!! The source type 'xdm_t' can write to a 'dir' of the following types:
# xdm_rw_etc_t, root_t, tmp_t, var_t, user_fonts_t, user_tmpfs_t, xdm_spool_t, fonts_cache_t, user_home_dir_t, locale_t, var_auth_t, tmpfs_t, var_spool_t, var_lib_t, user_tmp_t, var_run_t, xdm_tmp_t, auth_cache_t, xdm_tmpfs_t, xserver_log_t, var_log_t, xdm_log_t, pam_var_run_t, xdm_var_lib_t, xdm_var_run_t, xdm_home_t, pam_var_console_t, pcscd_var_run_t, var_lock_t, xkb_var_lib_t, root_t

allow xdm_t admin_home_t:dir { write add_name };
allow xdm_t admin_home_t:file { create open append };
