Access is denied when Horizon Client connects with RADIUS two-factor authentication.
A Horizon Client connection using RADIUS two-factor authentication displays Access Denied.
RADIUS does not receive a reply from the RADIUS server, causing Horizon 7 to time out.
The following common configuration mistakes most often lead to this situation:
The RADIUS server has not been configured to accept the View Connection Server instance as a RADIUS client. Each View Connection Server instance using RADIUS must be set up as a client on the RADIUS server. See the documentation for your RADIUS two-factor authentication product.
The shared secret values on the View Connection Server instance and the RADIUS server do not match.
