When set to True, Secure Socket Layer (SSL) file access processing will request a certificate from the client. If AccessSSLRequireCert is False, access will continue if the client does not have a certificate. Note that some versions of Internet Explorer will close the connection if the server requests a certificate and one is not available, whether or not AccessSSLRequireCert is also set to True. AccessSSLNegotiateCert is one of the SSL file permission flags contained in the AccessSSLFlags property.
The following table describes this property:
| Data type | Boolean |
