Hi,
You need to refer to ad.properties from your profile, in this profile you need to specify credentials and settings to access the active directory.
For example, how can the implementation guess where your active directory is? what is the user that is to be used to access it?
Please follow extension configuration[1] and create two extensions per documentation.
1. authn - authentication
2. authz - authorization.
Both extensions should refer to your profile[2] that specifies the required information.
Regards,
Alon
