Description Bruno Roberto Zanuzzo 2014-07-31 06:25:17 UTC
Description of problem:
SELinux is preventing sddm from 'write' accesses on the file /etc/sddm.conf.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow sddm to have write access on the sddm.conf file
Then you need to change the label on /etc/sddm.conf
# semanage fcontext -a -t FILE_TYPE '/etc/sddm.conf'
where FILE_TYPE is one of the following: abrt_var_cache_t, afs_cache_t, anon_inodefs_t, auth_cache_t, auth_home_t, cache_home_t, cgroup_t, config_home_t, data_home_t, dbus_home_t, etc_runtime_t, faillog_t, fonts_cache_t, gconf_home_t, gkeyringd_gnome_home_t, gkeyringd_tmp_t, gnome_home_t, gstreamer_home_t, icc_data_home_t, initrc_tmp_t, initrc_var_run_t, krb5_host_rcache_t, lastlog_t, locale_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, pam_var_console_t, pam_var_run_t, puppet_tmp_t, security_t, sysfs_t, systemd_passwd_var_run_t, user_cron_spool_t, user_fonts_t, user_tmp_t, var_auth_t, wtmp_t, xauth_home_t, xdm_home_t, xdm_lock_t, xdm_log_t, xdm_rw_etc_t, xdm_spool_t, xdm_tmpfs_t, xdm_var_lib_t, xdm_var_run_t, xkb_var_lib_t, xserver_log_t, xserver_tmpfs_t. 
Then execute: 
restorecon -v '/etc/sddm.conf'

*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that sddm should be allowed write access on the sddm.conf file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep sddm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
