Yes, Authentication Services allow you to login with your AD account directly into UNIX machine. No NIS accounts are needed. One of the most common motivations for integrating Unix and Active Directory is to overcome the technical and security deficiencies in legacy NIS environments. There are several tools that can help you with this. There is a section called Migrating from NIS in the Authentication Services - Administration Guide. Please see the following link:
