You can set automatic authentication for a proxy server when accessing Bing Map, Move Map, and the Web Feature Service (WFS).
MapInfo Pro supports single sign-on authentication with proxy servers while accessing tile map services, such as Bing Map. MapInfo Pro signs on to the proxy server for you by automatically passing your Windows Authentication credentials (your Windows user name and password), so that you do not have to type your proxy user name and password.
Support for single sign-on authentication for proxy servers is in addition to our existing support for basic authentication for proxy servers. If you have your proxy server set up with basic authentication, then you still need to enter a user name and password. For automatic authentication, you must have NTLM, Kerberos, or Negotiate authentication set up on the proxy server, and your proxy access credentials must be the same as your Windows Authentication credentials.
This single sign on experience does not apply to Tile Server authentication when the Tile Server you are using requires you to sign on before accessing map tiles.
