Description Samium Gromoff 2013-08-05 05:25:47 EDT
Description of problem:
I am trying to run ejabberd with PAM authentication, but SELinux shoots down PAM-related machinery
during client authentication.

I have the following in my /etc/ejabberd/ejabberd.conf:
---- >8 ----
{auth_method, pam}.
{pam_service, "login"}.
---- 8< ----
SELinux is preventing /usr/lib64/ejabberd/priv/bin/epam from 'execute_no_trans' accesses on the file /usr/sbin/unix_chkpwd.

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

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