Description Hicham HAOUARI 2011-03-09 16:20:52 UTC
SELinux is preventing /usr/sbin/lxdm-binary from 'rename' accesses on the file /var/log/lxdm.log.

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

If you believe that lxdm-binary should be allowed rename access on the lxdm.log 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 lxdm-binary /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

restorecon /var/log/lxdm.log

Will fix the problem.

If it happens again, reopen the bug.
