403.7
Client certificate required
Description
Some web sites require you have a special "certificate" to access the site. This typically occurs with higher security sites, such as a corporate web site for employee access only. You need this certificate to access the site.
Example
Server Error
403.7 - Forbidden: SSL client certificate is required.
The page you are attempting to access requires your browser to have a Secure Sockets Layer (SSL) client certificate that the Web server will recognize. The client certificate is used for identifying you as a valid user of the resource.
Error messages will differ depending on the web server and if replaced by the web site designers.
Occurrences
Frequency is relative to other Internet warnings and errors.
