Description Guilherme de Almeida Suckevicz 2020-02-19 18:19:01 UTC 
OpenVPN Access Server 2.8.x before 2.8.1 allows LDAP authentication bypass (except when a user is enrolled in two-factor authentication).

Comment 1 David Sommerseth 2020-02-19 19:12:03 UTC 
This is NOT related to the community releases of OpenVPN.  This is related to the Access Server where the LDAP integration implemented, which is a component which is not open sourced.  The Access Server just builds on the OpenVPN community release under the hood for the core VPN functionality.  The management layer (where the LDAP authentication happens in this case) is what makes it the Access Server product; this management layer utilizes the management interface found in the core OpenVPN 2.x component.

From a Fedora and Red Hat products perspective, this ticket can be closed as not applicable.
