I am using an Active Directory account and want the proxy to authenticate with the credentials used to log into the computer. Auto proxy discovery doesn't work. I have it working now by checking HTTP and HTTPS proxies and putting in the IP and port along with the Active Directory name and password to use. This will be a problem when it comes time for a user to change their password and they will need to go into the proxy settings and change it there as well. I'm wanting the proxy settings to use whatever credentials are used to log into the machine.
