is expected on the other end of the connection.
If the gio.types.TlsCertificateFlags.BadIdentity flag is set in #GTlsClientConnection:validation-flags, this object will be used to determine the expected identify of the remote end of the connection; if #GTlsClientConnection:server-identity is not set, or does not match the identity presented by the server, then the gio.types.TlsCertificateFlags.BadIdentity validation will fail.
In addition to its use in verifying the server certificate, this is also used to give a hint to the server about what certificate we expect, which is useful for servers that serve virtual hosts.
