Version-Release number of selected component (if applicable):
lightdm-1.5.2-2.fc19.i686


How reproducible: every time


Steps to Reproduce:
1. Boot Fedora 19 Alpha TC6 XFCE Live spin.
2. Look in syslog /var/log/messages.
3. Invoke sealert as indicated.
  
Actual results:
localhost setroubleshoot: SELinux is preventing /usr/sbin/lightdm from create access on the file .dmrc.MWKGVW. For complete SELinux messages. run sealert -l <<UUID>>

Expected results: no complaint


Additional info:$ sealert -l <<UUID>>
SELinux is preventing /usr/sbin/lightdm from create access on the file .dmrc.MWKGVW.

*****  Plugin catchall (100. confidence) suggests  ***************************

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