Subject: [PATCH] Re-introduce --tls-remote for Fedora EPEL-6 and EPEL-7 only

This reverts commit 10ce637066f44e8ad9f4af000b8d0c2a4012236d.

To avoid breaking any existing OpenVPN installations using the
Fedora EPEL repository, this patch re-introduces this DEPRECATED
--tls-remote option for Fedora EPEL-6 and EPEL-7 ONLY. This is
only considered to be an exceptional patch and will not be part
of any upstream OpenVPN releases.

+Accept connections only from a host with X509 name

+.B name.
+The remote host must also pass all other tests
+of verification.
+
+.B NOTE:
+Because tls\-remote may test against a common name prefix,
+only use this option when you are using OpenVPN with a custom CA
+certificate that is under your control.
+Never use this option when your client certificates are signed by
+a third party, such as a commercial web CA.
+
+Name can also be a common name prefix, for example if you
+want a client to only accept connections to "Server-1",
+"Server-2", etc., you can simply use
+.B \-\-tls\-remote Server
+
+Using a common name prefix is a useful alternative to managing
+a CRL (Certificate Revocation List) on the client, since it allows the client
+to refuse all certificates except for those associated
+with designated servers.
+
+.B \-\-tls\-remote
+is a useful replacement for the
+.B \-\-tls\-verify
+option to verify the remote host, because
+.B \-\-tls\-remote
+works in a
+.B \-\-chroot
+environment too.
+
+.B Please also note:
+This option is DEPRECATED. It has been removed in upstream OpenVPN v2.4.0
+and have only been re-introduced into PowerEL7 for backwards
+compatibility purposes. It will NOT be provided in any newer major EPEL
+releases. So please make sure you support the new X.509 name formatting
+described with the
+.B \-\-compat\-names
+option as soon as possible by updating your configurations to use
+.B \-\-verify\-x509\-name
+instead.
