Test Active Directory Login Issue

How come ConnectionDetails.php script effects the Verify Credentials process?

For example and to explain my use case, I’m on a server that requires me to set the port as a PHP constant. When using the previous file I mentioned it overrides whatever appears in the port field in the admin menu (I believe the code even tells me this in the comments – Override the default portset by the blog or site admin) with your own custom value.
) So even though it says 389 in the field, in the logs it shows that its what the constant sets it as which in my case is 58287, this means ConnectionDetails.php around line 85 (the setPort function).

I also need to set the address a specific way because when using ldaps ldap_connect function ignores the optional port, so I have to also add the port value to the domain. So in that same file I change the setDomainControllers function value to my own – Override the default domain controllers (set by the blog or site admin) with your own custom value. I was able to do this to pass the credentials verification and save my settings, but I can’t use ConnectionDetails.php to change testing and the real authentication process when logging in.
