hi guys,
I hope you are all good.
I set up MCP for user authentication. We use it to indirectly authenticate by passing a special group to MWG and blocking requests without that group. Works just fine.
But since I set up MCP on ePO and MWG policy and settings as mentioned in this article (https://community.mcafee.com/t5/Documents/Web-Protection-Configuring-McAfee-Client-Proxy-MCP-for-Web...) I get login prompts for internal resources (our windows domain).

When I do not use MCP there is no problem with internal resources.
Is there something I did wrong or I missed to thing about?
Thanks in advance.
