I’m new to DNN world so would appreciate if someone can help me. I’m using DNN version 6.0

I’ve requirement to authenticate users from LDAP. I’ve downloaded DNN_ActiveDirectoryAuthentication version 5.0.2 and tried configuring using below details

Enabled=True

Provider=ADSIAuthenticationProvider

Authentication Type=Delegation

Root Domain=   DC=domain, DC=Com

User Name         =domain\username

But when I hit the Update Authentication Settings I’m getting lots of runtime error as user,

Error is currently unavailable. DotnetNuke.Services.Exceptions.ModuleLoadException

System.NullReferenceException: object reference not set to an instance of an object at Dotnetnuke.Authentication.ActiveDirectory.ADSI.Utilities.AddADSIPath(string path, Path ADSIPath) at

Dotnetnuke.Authentication.ActiveDirectory.ADSI.Utilities.AddRootEntry(Path ADSIPath)…

Please suggest if I’m doing something wrong here or there is some other mechanism to do this

Regards,
