1. The backend can work only with one Membership provider, so make sure that you have set the name of your AD provider in <security> configuration section
<security defaultProvider="DefaultSecurityProvider" cmsProvidersName="AD">
2. The AD role should have CmsAccess permissions ( Administration >> Permissions)
All the best,
