If you want to let the client in, do a C<< $myserver->sendOK() >>. Otherwise, use C<< $myserver->sendError() >> as described below.

=head2 Connection Establishment with Subclassing

If you are subclassing C<DBIx::MyParse>, the way C<DBIx::MyParse::DBI> does, to establish a connection you call:

=item C<< $myserver->handshake() >>

which completes the handshake between the two parties. The return value will be C<undef> if some I/O error
occured, or the result of the client authorization routine. When the client sends its credentials, the
module will call:

=item C<< $myserver->authorize($remote_host, $username, $database) >>

whose default action is to accept only localhost connections regardless of username or password. You should
override this method to install your own security requirements. If your C<authorize()> returns C<undef>, the
connection will be rejected, if it returns anything else, the connection will be completed and the return
value will be passed back to the caller of C<handshake()>. You can use this return value to communicate the
access rights the particular user is entitled to, so that your script can know them and enforce them.
