When access is denied due to SSL being missing, error message doesn't tell you

When an attempt is made to log into mysql with a user that requires SSL, and the client does not use SSL, the following error message is displayed:

170105 23:24:49    16 Connect   user@docs.example.com as anonymous on 

                   16 Connect   Access denied for user 'user'@'docs.example.com' (using password: YES)

                   17 Connect   user@docs.example.com as anonymous on 

While the error message confirms that a password was present, the error message does not confirm whether SSL is present, and this causes significant confusion, particularly among people who are not DBAs.

The error message needs to be updated to include:

• Whether a password was used (yes/no).
• Whether SSL/TLS was used (yes/no).
• Whether an SSL client certificate was used (yes/no).
