I am setting up a lab environment for adfs. I have a web proxy , DC and adfs server and i was able to set up the adfs with web proxy without any problem. Now i want to use office 365 with my adfs according to the instructions i was following to install Azure AD, i need to install the Azure AD on my th adfs server which i did. But the problem is i get this error message "The provided credentials are valid, however we were unable to establish connection to the local computers forest. Please make sure UDP and TCP ports 389 are open in Doman Controlla associated with the current local computers forest" at Connect to AD DS when i put the domain credentials. I tried turning of the firewalls on all VMS but didnt help. Im stuck now.
` Does anyone know what i did / doing wrong and can help?
