We have a Windows server 2012 R2 which is our Domain controller and has Active Directory on it. I have to integrate Cisco Meraki Dashboard with this server for authenticating the users with their AD credentials. I have everything configured on the Meraki Dashboard to contact the server, Essentially, what happens is that Dashboard and server will communicate on TLS, port 3268 and create the binding. For this to happen, On my windows server (DC) I need to provide the certificate for TLS connection. I created the certificate with all required parameters and imported them to personal, Trusted CA certs store in MMC snap (Don't have IIS installed). Now, when I do the testing from the Meraki Dashboard, It looked like it detected the server but it now has problems with my credentials. I am using the Domain Admin credentials, not sure what is wrong, any help would be appreciated.
