Apache SSL authentication connection is not permitted for expired certificate even if SSLVerifyClient is optional -

When I try to connect to the directory on Apache via HTTPS using SSL authentication authentication, where SSLVerifyClient is set to Optional

, connection is not permitted for the expiry of the certificate, but without the certificate it is.

Do anyone know how to allow connections with the expired certificate for clients? Even if the user is allowed without authentication.

I use the application and certificate of certification for the certificate without the certificate and if the certificate is expiring (is finished), then it will be renewed (of course other verification ) It works on IIS and I need to move Apache into practice.

Thanks for the suggestions.

SSLVerifyClient is set to optional

This means that the client certificate will be requested. Admission is provided if the customer does not provide the certificate but if the client does not provide a certificate and this certificate can not be verified then access is not granted. I believe that this behavior may seem silly, but how does it happen.
