We have been getting staff to register themselves. Remaining staff will be migrated accross into the staff directory from the existing one on the current site.
There are various plugins available to will allow you to integrate WordPress login with your active directory.
There are also plugins that will allow you to import users from a CSV file.
And plugins too to add a login widget (we’re using “Sidebar login” on some intranets).
All of my current clients are using inbuilt WordPress accounts and have imported their staff in bulk from a spreadsheet, allowing new staff to register online.
