I install openvpn 2.2.2 with Centos 6.2 x86_64 with rpm of rpmforge and try to use pam_mysql to authorize.<br />
<br />
When setenforce to Pemissive everything is working fine.<br />
<br />
but setenforce to Enforcing the auth is failed.<br />
<br />
the follow is the audit.log when selinux is enforcing.<br />
<br />

<br />
and the follow is the audit.log when selinux is permissive<br />
