Description Samium Gromoff 2013-08-05 08:50:24 UTC
Description of problem:
I'm trying to run ejabberd, and for some reason SELinux shoots it down during startup.

I have PAM authentication enabled, like that:

---- >8 ----
{auth_method, pam}.
{pam_service, "login"}.
---- 8< ----
SELinux is preventing /usr/lib64/erlang/erts-5.10.1/bin/epmd from 'write' accesses on the file /run/lock/ejabberdctl/ejabberdctl-1.

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore epmd trying to write access the ejabberdctl-1 file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/lib64/erlang/erts-5.10.1/bin/epmd /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that epmd should be allowed write access on the ejabberdctl-1 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 epmd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
