Assume X is a web server. And Y is a TMG server.
All incoming request from outside (WAN) , will have to go through Y first before reaching X .
X has its own form for authentication but we wanted to use our AD for authentication . If i test from internal , whenever a user type the URL of X, the page will load without asking any username and password. I assume this is because the AD authentication.
But now , when i test from outside ,the form will appear and asking for credentials.That is fine but the problem is username and password required belong to the local X database not the AD. It won't accept AD login . Looks like it doesn't integrate well will LDAP server define in Y .
I have configure Y listener to use authentication but failed. Is there any place that I miss to configure in Y ?
