We currently have Mixed Mode Authentication enabled. When a new user logs into the system, Kentico will check to see if they can be authenticated via AD and create them an account locally with the "IsDomainUser" checked if all goes well.

Is there an option to change this behavior such that if a user does not exist in Kentico, Kentico will not create one? I still want to authenticate via AD, but if a pre-existing user does not exist I would like AD to not create one and fail the authentication.

Thanks
