When you are converting an existing library to use Active Directory group security you need to map the existing users to their Active Directory User names.
- Open the library using Author-it Administrator, then go to Security > User and Group Accounts...
- Select the Users tab.
- Select the user from the Author-it User drop down list.
- Type the user's Active Directory details in the Active Directory User text box.
- Make sure the user is mapped to the correct group membership role.
- Save your changes.
